Question #N875
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. The diameter of the circle is twice the radius, or 10 units. The area of the square is the side length squared, so the area of the square is 10^2 = 100 square units.
