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.

Step-by-step 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=(1)/(3)\pi r^2h`

The surface area of cone is determined as

`S=\pi r(r+√(h^2+r^2))`Answer

Hence the answers are

`\begin{gathered} V=(1)/(3)\pi r^2h \\ S=\pi r(r+√(h^2+r^2)) \end{gathered}`
