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