Question

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.
A. 1,214 in.2

B. 2,040 in.2

C. 2,647 in.2

D. 1,931 in.2

Answer 1

help please

Answer 2

The distance around is 2*pi*radius. The area of the side is that distance multiplied by the height. If it helps, think of the side of the cylinder cut along the longitudinal axis, and laid out on the table as a rectangle.

If we do a two significant figure estimate, we get 6*13*15, which is close to 1200.
