Find the radius of the sphere whose volume is 562.5π cm3

A 4.5 Correct Answer Incorrect Answer
B 7.5 Correct Answer Incorrect Answer
C 3.5 Correct Answer Incorrect Answer
D None of these Correct Answer Incorrect Answer

Solution

Let the radius of the sphere be 'r' cm. Volume of sphere = (4/3) × π × r3 So, 562.5π = (4/3) × π × r3 Or, (3375/8) = r3 So, r = (15/2) = 7.5
