find the volume of a sphere with a radius of 9 cm
The formula to calculate the volume of a sphere is V = (4/3)πr³, where r is the radius of the sphere.
Given that the radius of the sphere is 9 cm, we can plug this value into the formula:
V = (4/3)π(9)³
V = (4/3)π(729)
V = 3053.63 cm³
Therefore, the volume of a sphere with a radius of 9 cm is approximately 3053.63 cm³.
