Question

A can of corn has a diameter of 14 cm and is 18.2 cm tall. How much metal is required to make the can?

Answer 1

1108.67 square centimeters

Explanation:

Surface Area = 2πr² + 2πrh

Radius = diameter / 2 = 14 cm / 2 = 7 cm

Surface Area = 2π(7 cm)² + 2π(7 cm)(18.2 cm)

Surface Area ≈ 2π(49 cm²) + 2π(127.4 cm²)

Surface Area ≈ 307.86 cm² + 800.81 cm²

Surface Area ≈ 1108.67 cm²

Therefore, approximately 1108.67 square centimeters of metal are required to make the can.
