Question

3. A sphere has a diameter of 12 cm.

a. Find the surface area of the sphere in exact form.

b. Find the volume of the sphere in exact form.

c. What is the ratio of the Surface Area to the Volume in lowest terms.

Answer 1

To find the surface are of a sphere you need to do:
SA = 4π r²

To find the volume of the sphere you need to :
V = 4/3 π r³

i am not too sure for the ratio

hope the method above helps you !!

Answer 2

the volume is ≈902.06.
