A circle with radius 5 is inscribed in a square. What is the area 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, the diameter is 10. Therefore, the side length of the square is 10, and the area of the square is 10 * 10 = 100.
