Answer:

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:

$90\pi in^2$

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;

$A_L=2\pi * 5* 9$

$A_L=90\pi in^2$
