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 PI.

A. 76.93 m squared
B. 65.94 m squared
C. 10.99 m squared
D. 16,642 m squared

3 answers

To find the total surface area of one stool, we need to calculate the area of the top, bottom, and side separately.

1. Area of the top and bottom (two circles):
A = 2 * π * r^2
A = 2 * 3.14 * (0.5)^2
A = 3.14 * 0.25
A = 0.785 m^2 (for each)

2. Area of the side (cylinder):
A = 2 * π * r * h
A = 2 * 3.14 * 0.5 * 3
A = 3.14 * 1.5
A = 4.71 m^2

Total surface area of one stool:
0.785 + 0.785 + 4.71 = 6.28 m^2

Since Giavonna has 7 stools to paint, the total surface area she has to paint is:
6.28 * 7 = 43.96 m^2

Therefore, the correct answer is not provided in the options. The correct total surface area Giavonna has to paint is 43.96 m^2.
