A circle with a radius of 5 centimeters is inscribed in a square. What is the area, in square centimeters, of the square?
A. 20
B. 25
C. 50
D. 100
Correct Answer is: D
The diameter of the circle is equal to the side length of the square. Since the radius of the circle is 5 centimeters, the diameter is 10 centimeters. Therefore, the side length of the square is 10 centimeters, and the area of the square is 10^2 = 100 square centimeters.
