Question

What is the lateral area of the cylinder?

Answer 1

Answer:

A. 622.04 ft²

Step-by-step explanation:

The lateral area of a cylinder is the area on the outside, meaning if you would cut open a cylinder longitudinally, and folded it open, the rectangle that remains is the lateral area of the cylinder.

The formula for the lateral area of a cylinder is:

$A_{l} = 2\pi *r*h$

Where 2πr represents one side of the rectangle, and h represents the other.

$A_{l} =2*\pi *11*9\\A_{l}=622.0353ft^{2}$

A ≈ 622.04 ft²

Answer 2

   
D = 22ft
h = 9 ft

Lateral area of the cylinder = π × D × h = 3,14 × 22 × 9 = 621,72 ft²
