A circle with a radius of 6 has a square inscribed inside of it. What is the area of the black region?
A) 23π - 31
B) 36π - 72
C) 63π - 42
D) 24π - 16
E) 30π - 62
Area of black region = Area of O - Area of square
Side of a square will be 6\(\sqrt{2}\), Since the present triangular region will be a 45-45-90
Area of black region = pi r^2 - s^2
36π - 72
Answer B
