To calculate the amount of wrapping paper needed for each gift, we first need to find the lateral surface area of the cylinder.
The lateral surface area of a right circular cylinder is calculated using the formula:
Lateral Surface Area = 2πrh
where r is the radius of the cylinder and h is the height.
Given that the diameter of the cylinder is 6 inches, the radius (r) is half of the diameter, so r = 6/2 = 3 inches.
Plugging in the values, we get:
Lateral Surface Area = 2 * 3.14 * 3 * 12
Lateral Surface Area = 2 * 3.14 * 3 * 12
Lateral Surface Area = 2 * 3.14 * 36
Lateral Surface Area = 226.08 square inches
Therefore, Olga will need 226.08 square inches of wrapping paper for each gift she is going to wrap.
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 n. (1 point)
inches?
