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.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
