Question

A deli wraps its cylindrical containers of hot food items with plastic wrap. The containers have a diameter of 3.5 inches and a height of 4 inches. What is the minimum amount of plastic wrap needed to completely wrap 6 containers? Round your answer to the nearest tenth and approximate using π = 3.14.

44.0 in2
63.2 in2
379.2 in2
505.5 in2

Answer 1

(c) 379.2 in²

Explanation:

You want to know the total surface area of 6 cylinders of diameter 3.5 inches and height 4 inches.

Area

The area of a cylinder in terms of diameter and height can be found by ...

A = πd(d/2 +h)

The area of 6 cylinders with d=3.5 and h=4 is ...

6A = 6π(3.5 in)(3.5 in/2 +4 in) ≈ 379.2 in²

The minimum wrap needed is 379.2 square inches.
