Respuesta :

use 3.15 for tt. 62.8 inches^2 I beieve

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:

[tex]A_{l}[/tex] = 2.Ï€.r.h, where

r is the radius;

h is the height;

Substituing and resolving:

[tex]A_{l}[/tex]  = 2.π.2.5

[tex]A_{l}[/tex] = 20Ï€

[tex]A_{l}[/tex] = 62.8

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