Question

# A circle is inscribed in a square as shown. If the radius of the circle is 4 cm, what is the area of the remaining square? (Use π=227) 14 cm2 13.63 cm2 13.72 cm2 14.28 cm2

Solution

## The correct option is C 13.72 cm2 Since the radius of the circle is 4 cm, the length of the square's side will be the diameter of the circle which is 8 cm. Area of square =8×8=64 cm2 Area of circle =227×4×4=50.28 cm2 Area of the remaining square = 64 - 50.28 = 13.72 cm2
