Question #N1001
A circle with a radius of 5 cm 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 cm, the diameter is 10 cm. Therefore, the side length of the square is 10 cm, and the area of the square is 10² = 100 square centimeters.
