Find the volume of a sphere with a radius of 9 cm. Leave your answer in terms of pi.
The volume of a sphere is given by the formula
V = (4/3)πr^3
where V is the volume and r is the radius.
Substituting the given radius r = 9 cm into the formula, we have
V = (4/3)π(9)^3
V = (4/3)π(729)
V = (2916/3)π
V = 972π
Therefore, the volume of the sphere with a radius of 9 cm is 972π cubic cm.
