Answer:

18.265

Step-by-step explanation:

calculate area of circle: pi8^2 = 201.06

calculate area of triangle: (8x8)/2 = 8x4 = 32

divide area of circle by 4 (as the triangle occupies 1/4 of the cirlce) and then subtract 32 from this value: 201.06/4 = 50.265, then 50.265 - 32=18.265

Hope this helps!
