Find the volume of the sphere express your answers in terms of pi

  Exact volume is   2304pi    cubic yards

Work Shown:

V = (4/3)*pi*r^3 is the volume of any sphere with radius r

We have r = 12 as our radius

V = (4/3)*pi*12^3

V = (4/3)*pi*1728

V = (4/3)*1728*pi

V = 2304pi   is the exact volume in terms of pi

To get the approximate volume, replace pi with 3.14 or any decimal approximation of pi, and use your calculator. Or you can hit the pi button on your calculator to have the calculator use its stored value.

If you use pi = 3.14, then the approximate volume is roughly 7234.56 cubic yards.

72

Step-by-step explanation:

So draw a square and make an right angle in one of  the squares  corners! so basically what ever is on one side it's on the other side so theirs two 12 so 144 the dived my 2 which is 72!

I don't remember this sorry!
