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.
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
