Answer:
(x+3)²+(y+5)² = 36
Step-by-step explanation:
The general equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the centre of the circle
r is the radius of the circle
Given
Centre (-3, -5)
a = -3 and b = -5
radius r = 6units
Substitute
(x-a)²+(y-b)² = r²
(x-(-3))²+(y-(-5))² = 6²
(x+3)²+(y+5)² = 36
hence the required equation is (x+3)²+(y+5)² = 36
The equation of a circle that represents a circle with a center at (-3, -5) and a radius of 6 unit is (x + 3)² + (y + 5)² = 36
Equation of a circleThe general equation of a circle is expressed as follows:
(x-a)²+(y-b)² = r²
where
r = radius of the circlea and b are the centre of the circleTherefore,
a = -3
b = -5
r = 6
Hence,
(x - (-3))² + (y - (-5))² = 6²
(x + 3)² + (y + 5)² = 36

A shipment of 5 boxes of toys weighed
34.53 pounds. Each box measures the same
weight, so what's the weight of 1 box?
Answer:
Each box weighs 6.906 pounds.
Step-by-step explanation:
We know the total weight of the boxes. We also know how many boxes we have. To find the weight of one box, we want to divide the total weight by the total number of boxes.
34.53 / 5
= 6.906
Each box weighs 6.906 pounds.

2. A circular patio has a diameter of 18 feet. How
many square feet of tile will it take to cover the
patio?
Answer: So to cover the patio it would take 255 whole tiles. 254.469 if you want to be exact.
Step-by-step explanation:
When finding flooring needed we are finding for area. We know the formula for finding the area of a circle is A=[tex]\pi r^{2}[/tex] so we plug in our known variables...
we know r because radius is half of diameter and diameter was given in problem. So half of 18 is 9.
r=9
A=[tex]\pi 9^{2}[/tex]
A=[tex]\pi[/tex]81
A=254.469

Find the volume of a cone with a base radius of 5 in. and a height of 12 in.
Answer:
V = 314
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
Given:
r = 5
h = 12
Work:
V = πr²(h/3)
V = 3.14(5²)(12/3)
V = 3.14(25)(4)
V = 314
Answer:
The volume of the cone is 311.1in³.
Step-by-step explanation:
V = ⅓Bh where B = πr²
V = ⅓πr²h
V = ⅓(22/7)(5²)12
V = 0.33(3.142)(25)12
V = 311.1in³

the lenght of an arc in a circle with diameter 10 inches is 1.25π inches. determine the measure of the arc.
Answer:
[tex]the \: angle \: is \: 0.25\pi[/tex]
Step-by-step explanation:
the arc length is equal to the radius x angle (in radians)
[tex]s=ra[/tex]
s= arc length, r= radius and a= the angle
solve for a ; a= s/r; a=
[tex]1.25\pi/5[/tex]
The measure of the arc is 0.25π.
Important information:
Diameter of a circle = 10 inches.Length of arc = 1.25πMeasure of arc:The formula for arc length is:
[tex]s=r\theta[/tex]
where s is the arc length, r is the radius and [tex]\theta [/tex] is the measure of arc in radian.
The diameter of a circle is 10 inches. So, the radius is 5 inches.
[tex]1.25\pi=5\theta[/tex]
[tex]\dfrac{1.25\pi}{5}=\theta[/tex]
[tex]0.25\pi=\theta[/tex]
Therefore, the measure of the arc is 0.25π.

The Correlation Coefficient, R value gives a measure of the degree of correlation between two variables, the dependent and independent variable. The correlation Coefficient value ranges from - 1 to 1. With negative values depicting a negative relationship and positive values meaning a positive relationship. The closer the R value is to + or - 1, the higher the strength of the relationship. With a value of 0 meaning 'no correlation'.
The correlation Coefficient value of the data above is 0.603, this gives a fairly strong positive correlation

Ben wants to buy a new car stereo and he has already saved some money. He used this inequality to represent the amount he still has to save to be able to buy the stereo, where a represents the amount still left to save.
a + 212 greater-than-or-equal-to 365
If Ben saves $15 a week for the next 10 weeks, will he be able to buy the stereo and why?
Answer:
Since Ben would have $362, he won't be able to buy the stereo as he needs to have an amount greater than or equal to 365.
Step-by-step explanation:
First, you need to determine the amount that Ben would have after saving $15 for the next 10 weeks:
$15*10=$150
Now, the inequality indicates that the amount left to save plus 212 should be greater than or equal to 365, so you have to add up 212 plus the amount Ben will save in the next 10 weeks to be able to determine if he would be able to buy the stereo:
150+$212=$362
Since Ben would have $362, he won't be able to buy the stereo as he needs to have an amount greater than or equal to 365.
