To calculate the amount of wrapping paper needed for each gift, you need to find the total surface area of the cylinder.
The formula for the surface area of a cylinder is:
2πr(h + r), where r is the radius and h is the height.
Given that the diameter is 6 inches, the radius (r) would be half of that, which is 3 inches.
Plugging in the values into the formula:
Surface Area = 2 * 3.14 * 3 * (12 + 3) = 2 * 3.14 * 3 * 15 = 282.6 inches^2
Therefore, Olga would need 282.6 square inches of wrapping paper for each gift she wraps.
bot 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)
