A spherical tank at a water purification plant holds 36π cubic meters of treated water. What is the radius of the tank?
Show answer & explanation
Correct answer: A
Explanation
Given:
Volume of the sphere = 36π cubic meters
By the formula:
Volume of the sphere = (4/3)πr³
(4/3)πr³ = 36π
(4/3)r³ = 36
r³ = 27
r = 3
Radius of the tank = 3 meters
