Question

Find the volume of the sphere with a diameter of 18. Express your answer in terms of pi

Answer 1

Answer:

V = 972π cubic inches :)

Step-by-step explanation:

The formula for the volume of a sphere is

V = (4/3)πr3

If the diameter is 18 inches, then the radius is 9 inches.  Substituting 9 in for r gives us a volume of:

V = (4/3)π(9)3

V = (4/3)π(729)

V = 972π cubic inches

Hope this helps!
