Question

Use the net to find the lateral area of the cylinder. Give your answer in terms of pi.

Answer 1

The correct answer option is 90
`\pi inches^2`.

Explanation:

We are given a cylinder with a radius of 5 inches and a height of 9 inches and we are to find the lateral area of this cylinder.

We know that the formula of the lateral area of a cylinder is given by:

Lateral area of cylinder =
`2 \pi r h`

Substituting the given values in the formula to get:

Lateral Area =
`2\pi *5*9` = 90
`\pi inches^2`

Answer 2

`90\pi in^2`

Explanation:

The lateral area of the cylinder is given by;

`A_L=2\pi rh`

The radius of the cylinder is
`r=5in.` and the height is
`r=9in.`

Substitute the values to get;

`A_L=2\pi * 5* 9`

`A_L=90\pi in^2`
