Question

Find the volume of the sphere A) 20.3 cm^3B) 27.6 cm^3C) 38.9 cm^3D) 44.6 cm^3

Answer 1

ANSWER :

D. 44.6 cm^3

EXPLANATION :

The volume formula of sphere is :

$V=\frac{4}{3}\pi r^3$

From the problem, the radius of the sphere is 2.2 cm.

Using the formula above :

$\begin{gathered} V=\frac{4}{3}\pi(2.2)^3 \\ V=44.60cm^3 \end{gathered}$
