Answer:
<u>a= 84.83</u>
Step-by-step explanation:
so remember this: my teacher taught me this amazing strategy to remember the formulas
<u>C=πd : cherry pie delicious</u>
<u>a=πr² : apple pie are too</u>
and 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=πr²
you get: a=π6²
follow 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 answer
you do the exponent first then multiply by pie.
you get: 6²=36
36xπ=113.09733552923255658465516179806
round that answer to the nearest tenths and get: 113.1
now time to find the area of the smaller circle!!!
fill in a=πr² and get: a=π3²
its 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=π3²
a=π9
a=28.274333882308139146163790449516
round and get: 28.27
now subtract the the bigger circles area and the smaller circles area:
113.1 is the bigger circles area
28.27 is the smaller circles area.
113.1 - 28.27 = 84.83
<u>a=84.83</u>
<u></u>
