What is the area of the shaded region?
256 - 64pi = 54.94 My answer isn't one of the choices...
your answer is correct; it's just that this problem is very misleading and confusing.
Notice that if you replace pi with 3.14 you get 16*16-8*8*3.14 = 55.04.
I got that answer too Lol. Thanks for explaining it ●︿●
