Question #N722
A circle with a radius of 5 is inscribed in a square. What is the area 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. The diameter of the circle is twice the radius, so the diameter is 10. The area of a square is equal to the side length squared, so the area of the square is 10^2 = 100.
