Olga is making presents for her teachers and needs to wrap them. She places the gifts in a right circular cylinder with a height of 12 inches and diameter of 6 inches. How much wrapping paper does she need for each gift she is going to wrap? Use 3.14 for π.(1 point)

Question

inches2

Answer 1

To find the amount of wrapping paper needed, we first need to find the surface area of the cylinder.

The formula for the lateral surface area of a cylinder is 2πrh, where r is the radius and h is the height.

Given that the diameter is 6 inches and the radius is half of that, so the radius (r) is 6/2 = 3 inches.

Plugging in the values, we get:

Lateral surface area = 2 * 3.14 * 3 * 12
Lateral surface area = 6.28 * 36
Lateral surface area = 226.08 inches2

Therefore, Olga will need 226.08 inches2 of wrapping paper for each gift she wraps.
