Question

Find the volume of the sphere to the nearest tenth

Answer 1

Given:

Radius = 1.1 cm

Find-: Volume of a sphere

Sol:

The volume of a sphere is:

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

So the volume is:

$\begin{gathered} V=\frac{4}{3}\pi r^3 \\ \\ V=\frac{4}{3}\pi(1.1)^3 \\ \\ V=\frac{4}{3}\pi\times1.331 \\ \\ V=1.7746\pi \\ \\ V=5.6\text{ cubic centimeter} \end{gathered}$

So, the volume is 5.6 cubic centimeter.
