Final answer:
The volume of the sphere with a radius of 9 cm is 3056π cm³.
Step-by-step explanation:
The volume of a sphere can be calculated using the formula V = (4/3)πr³, where V is the volume and r is the radius of the sphere.
In this case, the radius is 9 cm.
Plugging this value into the formula, we get :
V = (4/3)π(9 cm)³.
Simplifying further, we have:
V = (4/3)π(729 cm³)
= 3056π cm³.
Therefore, the volume of the sphere with a radius of 9 cm is 3056π cm³.
