A square is inscribed in a circle with a radius of 5 units. What is the area of the square?

✓ Correct Answer: Option C

The diagonal of the inscribed square is the diameter of the circle, which is 2*5 = 10. If 's' is the side of the square, s^2 + s^2 = 10^2, so 2s^2 = 100. Thus, the area s^2 = 50.
