The square root of -3 is 1.73205081
50x513 is 25,650, 25,650x2 is 51,300
Are you trying to find n?
Ok so to answer this, we first need to figure out the area of both circles
we will use the formula A=πr²
so our two areas end up being 121π and 81π
now all we do is subtract the smaller from the larger
121π - 81π = 40π
shaded region = 40π
2 and 11/100. I think that's as simple as it gets in a mixed number form
