Find the area of the shaded region in the figure below, if the radius of the outer circle is 12 and the radius of the inner circle is 8. Keep your answer is terms of n

339.29

Step-by-step explanation:

total circle area = 452.39

why?

because area of circle equation = pi * r^2

pi is the weird symbol. pi = 3.14

r = radius

r = 12

3.14 * 12^2 = 452.389342

simplified to 452.39.

but that is the whole thing.

we want only the shaded area.

first we will find the area the not shaded bit. then we will minus the total area, 452.39, by the not shaded bit so we only have the shaded bit.

again, area of circle equation = pi * r^2

r = 6.

3.14 * 6^2 = 113.097336

this is the not shaded bit. it can be simplified to 113.1

total area - not shaded bit = shaded bit

452.39 - 113.1 = 339.29

sorry, i can't understand your question. will later if you describe more clearly!

: )

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
