The volume of a sphere is 36π cm3. What is the radius of the sphere?
Answer & explanation
Correct answer: option 4
We have,
Volume of sphere = \(\frac{4}{3}\)πr3
We have,
Volume of sphere = 36π cm3
According to the question,
= 36π = \(\frac{4}{3}\) × π × r3
= 9 = \(\frac{1}{3}\) × r3
= 27 = r3
= r = 3
