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?

Since Giavonna has to paint the top, bottom, and side of each stool, we can find the surface area of one stool and then multiply by 7 to get the total surface area.

Surface area of the top and bottom of one stool:
Area = πr^2
Area = 3.14 * (0.5m)^2
Area = 3.14 * 0.25
Area = 0.785 m2

Since there are two of them (top and bottom), the total area for both is: 0.785 * 2 = 1.57 m2

Surface area of the side of one stool:
Area = 2πrh
Area = 2 * 3.14 * 0.5m * 3m
Area = 9.42 m2

Total surface area of one stool:
1.57 m2 + 9.42 m2 = 10.99 m2

Total surface area of 7 stools:
10.99 m2 * 7 = 76.93 m2

Therefore, Giavonna has to paint a total surface area of 76.93 m2.
