volume for a sphere (ball) is 4/3 x PI x r^3
r = 6.3, r^3 = 6.3^3 = 250.047
volume = 4/3 x 3.14 x 250.047 = 1046.863
rounded to nearest hundredth = 1046.86 cubic inches

Answer:
equation;

Center (-4,2)
Radius is

Step-by-step explanation:
Since the x^2 and y^2 have the same coeffiecent this will be a circle in a form of

Where (h,k) is center
r is the radius
So first we group like Terms together

Add 7 to both sides


Since the orginal form of the equation of the circle has a perfect square we need to complete the square for each problem

and

so we have



To find our center, h is -4 and k is 2
so the center is (-4,2)
The radius is

So the radius is 3 times sqr root of 3.
Answer: 3
Explanation:
x + 7 = 5 x 2
you do 5(2) and get 10
plug in 10 and the equation looks like:
x + 7 = 10
from there you would subtract 7 from 7 and 10 to isolate x and get your answer of:
x = 3 :)
