Giavonna has to paint 7 cylinder-shaped stools, including the top, bottom, and side of each stool. If the height of each stool is 3 meters and the radius is 50 centimeters, what is the total surface area Giavonna has to paint? Use 3.14 for π .(1 point)

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

Given:
- Height (h) = 3 meters
- Radius (r) = 50 cm = 0.5 meters
- π = 3.14

Plugging in the values:
Surface area of one cylinder = 2 * 3.14 * 0.5 * 3 + 2 * 3.14 * 0.5^2
= 9.42 + 1.57
= 10.99 m^2

Giavonna has to paint 7 stools, so the total surface area she has to paint is:
Total surface area = 7 * 10.99
= 76.93 m^2

Therefore, the correct answer is 76.93 m2.
