Question #N1011

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

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 * 10 = 100 square centimeters.
