Question

How to fine the volume and surface area of a cone

Answer 1

Given

The diagram of cone is given which consists radius and height of cone.

Explanation

To determine the volume and surface area of cone.

Draw the diagram of cone.

Here r is the radius and h is the height.

Then the volume of cone is determined as

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

The surface area of cone is determined as

$S=\pi r(r+\sqrt{h^2+r^2})$Answer

Hence the answers are

$\begin{gathered} V=\frac{1}{3}\pi r^2h \\ S=\pi r(r+\sqrt{h^2+r^2}) \end{gathered}$
