Question

The art class is making wind chimes out of tin cans. Each can is 5 inches tall with a radius of 2 inches. The students have to paint the outside portions of the Cans they want to use in their windchimes.

What is the lateral area for one of the tin cans? Use 3.14 for pie

A) 62.8
B)125.6
C)31.4
D)87.92

Answer 1

Answer: A) 62.8

Explanation:

Since, the shape of the can is cylindrical,

And, the lateral area of the cylinder is,

`A = 2 \pi rh`

Where r = radius of the cylinder

h = height of the cylinder

Here, r = 2 inches, h = 5 inches

Hence, the the lateral area for one of the tin cans,

`A = 2\pi* 2* 5`

`A = 2* 3.14* 2* 5`

`A = 62.8\text{ square inches}`

⇒ Option A is correct.
