Question

Find the volume of the sphere having a radius of 9 cm.

a) 3053π cm³
b) 243π cm³
c) 729π cm³
d) 972π cm³

Answer 1

The volume of a sphere with a radius of 9 cm is 972π cm³.

Step-by-step explanation:

The volume of a sphere is given by the formula:

V = (4/3)πr³

where r is the radius of the sphere.

Given that the radius of the sphere is 9 cm, we can substitute this value into the formula:

V = (4/3)π(9 cm)³

V = (4/3)π(729 cm³)

V = 972π cm³

Therefore, the volume of the sphere is 972π cm³, which corresponds to option d).
