Question

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

Answer 1

Answer:

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

Step-by-step 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

Answer:

$90\pi in^2$

Step-by-step 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;

$A_L=2\pi \times 5\times 9$

$A_L=90\pi in^2$
