Question #N555
A circle with a diameter of 10 inches is inscribed in a square. What is the area, in square inches, 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 diameter is 10 inches, the side length of the square is also 10 inches. The area of a square is found by squaring the side length, so the area of the square is 10^2 = 100 square inches.
