Question

The art class is making wind chimes out of tin cans. Each can is 5 inches tall with radius of 2 inches. The students have to paint the outside portions of the all cans they want to use in their chimes.
What is the lateral area for one of the tin cans?

Answer 1

Use 3.15 for tt. 62.8 inches^2 I beieve

Answer 2

Answer: Lateral Area = 62.8 square inches

Step-by-step explanation: The tin can is a cilinder. Its lateral area has a retangular shape with width equal the area of a circle. So, to calculate it:

$A_{l}$ = 2.π.r.h, where

r is the radius;

h is the height;

Substituing and resolving:

$A_{l}$  = 2.π.2.5

$A_{l}$ = 20π

$A_{l}$ = 62.8

The lateral area of the tin can is 62.8 or 20π square inches.
