Question

What is the area of the shaded region?

Answer 1

Answer: B

Explanation:

α/360r²π=area BOC(part of circle with radius 6√2)

Area of triangle CDO= (r²/4√3)/2

Area of shaded region= Area of BOC-Area of triangle CDO

Area of shaded region=α/360r²π-r²/8√3

α=∡BOC=60

r=6√2

Area of shaded region=60/360*72π-72/8*√3=12π-9√3
