First, we need to calculate the surface area of the cylinder.
The formula for the surface area of a cylinder is:
A = 2πr(r + h)
where r is the radius and h is the height.
Given that the diameter is 6 inches, the radius (r) is half of the diameter, so r = 6 / 2 = 3 inches.
Plugging in the values:
A = 2 * 3.14 * 3(3 + 12)
A = 2 * 3.14 * 3(15)
A = 2 * 3.14 * 45
A = 282.6 square inches
So, Olga needs 282.6 square inches of wrapping paper for each gift.
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)
