A can of carrots has a diameter of 2.5 inches and a height of 3.5 inches. How many square inches of paper will be needed for the label on the outside of the can

Answer 1

The surface area of a cylinder can be calculated using the formula:
Surface Area = 2πr² + 2πrh

Given that the diameter of the can (which is also equal to twice the radius) is 2.5 inches, the radius (r) is 2.5/2 = 1.25 inches.
The height (h) of the can is 3.5 inches.

Substituting these values into the formula:
Surface Area = 2π(1.25)² + 2π(1.25)(3.5)
Surface Area = 2π(1.5625) + 2π(4.375)
Surface Area = 3.125π + 8.75π
Surface Area = 11.875π

Using the approximation of π as 3.14:
Surface Area ≈ 11.875 x 3.14
Surface Area ≈ 37.25 square inches

Therefore, approximately 37.25 square inches of paper will be needed for the label on the outside of the can.
