Answer 1
Answer:

Answer:

The volume of the sphere is 904.32\ cm^(3)

Step-by-step explanation:

we know that

The volume of the sphere is equal to

V=(4)/(3)\pi r^(3)

In this problem we have

D=12\ cm -----> given problem

Find the radius

r=12/2=6\ cm ----> the radius is half the diameter

substitute

V=(4)/(3)(3.14)(6^(3))=904.32\ cm^(3)
