Question

A cone has a height of 25in and a radius of 18in. Calculate the volume. Use pi = 3.14.

Answer 1

In order to calculate the volume of a cone, we can use the formula below:

$V=\frac{1}{3}\pi r^2h$

Where r is the base radius and h is the height of the cone.

So, using h = 25 in and r = 18 in, we have:

$\begin{gathered} V=\frac{1}{3}\cdot3.14\cdot18^2\cdot25\\ \\ V=8478\text{ in^^b3} \end{gathered}$

Therefore the volume is 8,478 in³.
