Question #N94
A circle with a radius of 5 units is inscribed in a square. What is the area, in square units, 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 units, the diameter is 10 units. Therefore, the side length of the square is 10 units, and the area of the square is 10^2 = 100 square units.
