A:

Answer:a= 84.83Step-by-step explanation:so remember this: my teacher taught me this amazing strategy to remember the formulasC=πd : cherry pie deliciousa=πr² : apple pie are tooand to find the area of the saded area, we need to find the area of the big circle and subtract that by the smaller circle area.so, area of the big circle:fill in the variables for a=πr²you get: a=π6²follow the pemdas, the order of operations. now on the state test don't write pemdas as your answer because people are stupid and they dont take that answeryou do the exponent first then multiply by pie.you get: 6²=3636xπ=113.09733552923255658465516179806 round that answer to the nearest tenths and get: 113.1now time to find the area of the smaller circle!!!fill in a=πr² and get: a=π3²its not 6 this time because that was the radius for the bigger circle. the smaller circles radius is half the size as the bigger circle so divide that by two and get 3.now solve:a=π3²a=π9a=28.274333882308139146163790449516round and get: 28.27now subtract the the bigger circles area and the smaller circles area:113.1 is the bigger circles area28.27 is the smaller circles area. 113.1 - 28.27 = 84.83a=84.83plz give me brainliesttt
