A circle is graphed on a coordinate grid. Its center is at (3, 4), and the circle passes through point (3, 1). What is the approximate area, in square units, of the circle? (Use 3.14 for π.)

Answers

Answer 1

Answer:

it is either 18.84 or 31.40

Step-by-step explanation:

just do it in your head

Answer 2

The area of the circle is 28.26 square units

The center of the circle is given as:

[tex](a,b) = (3,4)[/tex]

The circle passes through the following point

[tex](x,y) = (3,1)[/tex]

Start by calculating the radius using the following distance formula

[tex]r = \sqrt{(x -a)^2 + (y - b)^2}[/tex]

So, we have:

[tex]r = \sqrt{(3 -3)^2 + (4 - 1)^2}[/tex]

[tex]r = \sqrt{9}[/tex]

Square both sides

[tex]r^2 = 9[/tex]

The area of the circle is then calculated as:

[tex]Area = \pi r^2[/tex]

So, we have:

[tex]Area = 3.14 \times 9[/tex]

[tex]Area = 28.26[/tex]

Hence, the area of the circle is 28.26 square units

If segment RT bisects ∡QRS, m∡QRT = 5x – 9 and m∡SRT = 2x + 33, find m∡SR

Answers

Answer:

61 degrees

Step-by-step explanation:

m∡QRT=m∡SRT

5x – 9=2x + 33

3x=42

x=14

∡SRT=2x+33

∡SRT=2(14)+33

∡SRT=28+33

If OB= 2x+1 and
BR = 3x-10 then OR=

Answers

OB + BR = OR (because the line would go O, B, R and OR encompasses the whole thing with B in the middle.
So 2x + 1 (OB) + 3x -10 (BR) = OR
2x + 1 + 3x -10 = OR
(Simplify)
5x - 9 = OR

The table below contains data on how many pages were read for homework in Mr. Kaplinsky's third period. The equation of the line of best fit for the data is y = 28.3x + 4.8. Which two statements accurately describe the slope for the line of best fit? About 28.3 pages were read each hour. The most that any student can read is 4.8 pages per hour. For each additional hour spent reading, approximately 4.8 additional pages can be read. If a student starts reading faster, they will read 28.3 more pages in each additional hour they read. If a student reads for 1 hour longer than another person, they will have read approximately 28.3 more pages.

James wants to buy some CDs that cost $14 each and a DVD that costs $23. He has $65. Write an equation (in the Show your work area) and solve to find how many CDs he can buy. Include "CD" in your answer.

Answers

Answer:

Step-by-step explanation:

65-23= 42

42/14= 3

Answer:

14x+23 =65 x=3CDs

Step-by-step explanation:

So for any question where you need to write your own equation, it is first necessary that you determine what each number in the problem means in order to determine where they should go. James has $65 so the equation needs to be set equal to 65. The problem says he wants to buy a DVD for $23 so that would be a constant $23 spent regardsless of how many CDs he buys. We are trying to use the equation to determine how many CDs James can buy so the number of CDs is the x value at $14 each which would be 14x in the equation. so the equation would be the 14x for the unknown number of CDs, plus 23 for the constant DVD that James would buy set equal to the $65 he can use to buy everything.

To solve the equation, you must now isolate for x. To start, cancel out the +23 on the left side by subtracting 23 from both sides. This will leave 14x=42. You must then cancel the 14 by dividing both sides by 14 leaving your answer of x=3CDs.

I hope this helps.

The sides of two similar trapezoids are in a ratio of 1:3. The area of the smaller trapezoid is 12 squared inches. Find the area of the larger trapezoid

Answers

Answer:

108 sq in.

Step-by-step explanation:

The ratio of the areas is the square of the ratio of the sides.

Side ratio 1:3

Area ratio 1:9

The side of the larger trapezoid is 3 times the side of the smaller trapezoid.

The area of the larger trapezoid is 9 times the area of the smaller trapezoid.

9 * 12 sq in. = 108 sq in.

Refer to the diagrams below. You will have two measurements for each person.(An easy way to measure the length of a foot is to have your subject stand on a piece of paper. Then, trace their foot and measure the outline once they move off the paper.)To measure the forearm, measure inside the arm, between the wrist and the elbow.Part 2Organize your data and find the rate of change.Create a table of the measurements for your data.

( Round final answer to the nearest hundredth) Lab - Wave Properties in a Spring11-05The wave characteristics you will observe in this lab are common to all waves (water, light, sound,etc.). Use your prior knowledge and the book to fill in the following blanks, then go in the hall andperform the lab.A wave is a disturbance that moves through (propagates) through empty space or through a_____________. There are two types of waves. A _____________________ wave requiresmatter to travel. List some examples of this type:A _____________________ wave does not require a medium. Examples include:In order to start and transmit a mechanical wave, a source of _____________ and an_______________ medium are required. A single disturbance is referred to as a_______________, and a series of disturbances is a wave __________.The questions in bold are those you should observe directly. Others will be answered using the book.A. TYPES OF MECHANICAL WAVES: In the hall, stretch the slinky on the floor until it isstretched (but still loose). Practice sending single pulses down the slinky by popping your wristfrom the center to the side and back to the center. Then send a continuous wave train along asyour partner holds the other end still. A piece of ribbon should be tied to one coil. Watch themotion of this ribbon (representing a particle) as the wave travels through the spring.In this type of wave, the particles move (perpendicular, parallel)to the direction the wave travels. This type of wave is called a __________________ wave.Its pulses are called ________________ and ________________.Now send a pulse by quickly pushing the spring forward and pullingit back, as shown. This type of wave is called _______________. Watch the motion of the ribbon.In this type, the particles move _____________ to the direction the wave travels. Its pulsesare called _____________ and _____________. Label each.Note that all waves transfer _____________ without transferring _______________. Inmechanical waves, particles of the medium vibrate back and forth in simple harmonic motion whilethe disturbance (or _____________) moves from one place to another.B. WAVE SPEEDSend a large pulse, followed by a small one. Does one pulse catch up to the other? ______(Hint: The person who sends these waves should watch how the waves look when they return. Makesure that both pulses are large enough initially to make it back to the sender!) The size of thepulse is called the __________________ of the wave. Did the size affect the speed? ______Generate a single transverse pulse in the slinky, keeping the stretch constant. Using a stopwatch,time the journey of the pulse from one end to the other and back again. Take the average ofseveral trials. _________Without changing your positions on the floor (therefore keeping the _____________ the pulsetravels the same), pull the slinky tighter using only about 3/4 of the coils. This makes a completelydifferent medium through which the pulse will travel. Time the journey as before. ___________Does the kind of medium affect the speed of the pulse? ___________ Lab Wave Properties in a Spring ____________________PHYSICSFundamentals 2004, GPB11-06C.
