The radius of a sphere is 3 cm. Find, in terms of π, its volume.
- \(30\pi cm^3\)
- \(108\pi cm^3\)
- \(27\pi cm^3\)
-
\(36\pi cm^3\)
The correct answer is: D
Explanation
Given that radius = 3cm.
volume of sphere = \(\frac{4}{3}\times\pi\times r^3\)
= \(\frac{4}{3}\times\pi\times 3^3\)
= \(\frac{4}{3}\times\pi\times 27\)
= \(4\times\pi\times9\)
= \(36\pi cm^3\)
