    Subtract the area of the right triangle from the given area of the sector and you will get the shaded area (known as segment of a circle). What is the area of the right triangle? @dietrich_harmon

    81 is not the area of the triangle. Try again.

    All of these options --> . (20.25- 40.5 ft2 B. (20.25 - 81) ft2 C. ( 20.25 - 40.5 2 ) ft2 give negative areas. Area is not negative so that leaves one option.

    Yes, this was a good "tricky" question. We should have picked up on that negative business but better late than never. :)
