Question #N520
A circle with a radius of 5 centimeters is inscribed in a square. What is the area, in square centimeters, of the square?
A. 25
B. 50
C. 100
D. 200
Correct Answer is: C
Since the circle is inscribed in the square, the diameter of the circle is equal to the side length of the square. The diameter of the circle is twice the radius, or 10 centimeters. Therefore, the side length of the square is 10 centimeters, and the area of the square is 10^2 = 100 square centimeters.
