Renata is completing a craft project that involves covering only the lateral surface of a cylindrical container with fabric. The cylinder has a height of 12.8 in. and a radius of 15.1 in. To the nearest square unit, how much fabric does she need for this project? Use a calculator

Lateral Surface Area of a Cylinder = (2 • π • r • height)

Surface Area = 2 * PI * 15.1 * 12.8

= 1,214.4 square inches

Answer: [tex]1214\text{ in.}^2[/tex]

Step-by-step explanation:

Given: Height of cylinder = 12.8 in.

The radius of the cylinder = 15.1 in.

We know that the lateral surface area of a cylinder is given by :-

[tex]LA=2\pi r h[/tex]

Now, the lateral surface area of the given cylinder is given by :-

[tex]LA=2(3.14)(15.1)(12.8)\\\\\Rightarrow\ LA=1213.7984\approx1214\text{ in.}^2[/tex]

Hence, she need [tex]1214\text{ in.}^2[/tex] of fabric for this project.
