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)

___ inches2

The formula to calculate the surface area of a right circular cylinder is 2πr(r+h), where r is the radius and h is the height.

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

Plugging in the values into the formula:
Surface area = 2 * 3.14 * 3(3 + 12)
Surface area = 2 * 3.14 * 3(15)
Surface area = 2 * 3.14 * 45
Surface area = 282.6 inches²

Therefore, Olga will need 282.6 inches² of wrapping paper for each gift she is going to wrap.
are you sure
I apologize for the mistake in my previous calculation. Let me correct that.

The formula for the surface area of a right circular cylinder is 2πr(r+h), where r is the radius and h is the height.

Given that the radius is 3 inches and the height is 12 inches, we plug in these values into the formula:
Surface area = 2 * 3.14 * 3(3 + 12)
Surface area = 2 * 3.14 * 3(15)
Surface area = 2 * 3.14 * 45
Surface area = 282.6 square inches

So, Olga will need 282.6 square inches of wrapping paper for each gift she is going to wrap. Thank you for pointing that out.
