A circular lawn with a diameter of 20 square feet will be planted with grass seed. How many square feet are on the lawn?

31.4 ft squared
125.6 ft squared
314 ft squared
1,256 ft squared

Answers

Answer 1

Answer:

314 ft squared

Step-by-step explanation:

A = πr^2 = π · 102 ≈ 314.15927

Answer 2

Answer:

314.159265359 ft squared or 314.16 ft squared rounded to the hundredths place. The closest result is option C.

Step-by-step explanation:

The formula for finding the area of a circle is A=π×r^2.

Step 1: Find the radius which is half of the diameter. In this case, the radius is 10 feet.

Step 2: Square the radius that you found. In this case, the number will be 100ft or 10^2.

Step 3: Multiple this number by π, or 3.14 if your teacher allows it. So in this case, 100×π=314.159265359 or 314.16 rounded to the hundredths place. If you use 3.14... the answer is 314.

Step 4: You've got your answer. Hope this helps!

Answer:

∠ ABC = 87°

Step-by-step explanation:

∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so

2x - 17 + x + 32 = 180 , that is

3x + 15 = 180 ( subtract 15 from both sides )

3x = 165 ( divide both sides by 3 )

x = 55

Then

∠ DBE = x + 32 = 55 + 32 = 87° , thus

∠ ABC = ∠ DBE ( vertical angles  )

∠ ABC = 87°

You made Marcellus 3 times as tall as Dan but you dragged Marcellus’s eyes to be 1 times as far apart as Dan’s eyes. A scale giant would have the same multiple for both.

If Dan's eyes are 5 cm apart, how many centimeters apart should Marcellus's eyes be?

Answers

If you dragged Marcellus’s eyes apart 1x farther than Dan’s eyes then they would both have eyes that are 5cm apart because 5 x 1 = 5

Marcellus's eyes should be 5 cm apart

If Marcellus eyes are 1 times as far apart as Daniels eyes. We can write this mathematically as;

Marcellus eyes are 1x far apart as Dan's eyes.

If we spin this over, we are told that Dan's eyes is 5 cm apart. How far apart would Marcellus's be.

Marcellus eyes will be Dan's eyes divided by the mathematical equivalent we wrote the other time, which is 1 times.

Essentially, Marcellus's eyes will be just as wide as Dan's eyes

If you used π, 157.079632679 yards or 157.08 yards rounded to the hundredths place. If you used 3.14, the answer is 157 yards.

Step-by-step explanation:

The formula to find the perimeter of a circle is P=2×π×r.

Step 1: Find the radius. In this case, the radius is 25 yards as shown in the diagram.

Step 2: Since the formula only includes multiplication, you can multiply any of the factors. For simplicity, multiply your radius by 2 first. In this case, 2×25=50.

Step 3: Multiply your last number with π. In this case, 50×π=157.079632679 or 157.08 rounded the hundredths place. 50×3.14=157.

Step 4: You found the answer! Hope this helps.

Answers

Answer:

8 = 2x + 4collect like terms8 - 4 = 2x4 = 2xdivide both sides by 24/2 = 2x/2X = 2

Answer:

x=2 (answer should have a positive sign.)

Step-by-step explanation:

To solve this problem, you have to isolate the x from one side of the equation.

First, switch sides.

8=2x+4

2x+4=8

Subtract by 4 from both sides.

2x+4-4=8-4

Solve.

8-4=4

2x=4

Then, divide by 2 from both sides.

2x/2=4/2

Solve.

4/2=2

x=2

The solution is 2.
