The radius of the sphere with a volume of 121.5 (pi) cubic feet is: 4.5 ft.
What is the Volume of a Sphere?
Volume of a sphere = 4/3πr³, where r is the radius of the sphere.
Given:
Volume = 121.5π cubic feet
Radius (r) = ?
Thus:
4/3πr³ = 121.5π
4πr³ = 3(121.5π )
4πr³ = 364.5π
Divide both sides by π
4r³ = 364.5
r³ = 364.5/4
r³ = 91.125
r = ∛91.125
r = 4.5 ft
Thus, the radius of the sphere with a volume of 121.5 (pi) cubic feet is: 4.5 ft.
