Question

Find the volume of the right cone below in term of

Answer 1

Solution:

Given:

The volume of a cone is given by;

$\begin{gathered} V=\frac{1}{3}\pi r^2h \\ where; \\ h=21 \\ r=8 \\ \\ Hence, \\ V=\frac{1}{3}\times\pi\times8^2\times21 \\ V=448\pi\text{ cubic units} \end{gathered}$

Therefore, the volume of the cone is;

$V=448\pi\text{ }units^3$
