Area of sector=sectorfraction times area
sector fraction=angle/360

area=pir^2
r=10
area=pi10^2=100pi

so
5pi/100pi=xdeg/360
1/20=x/360
times both sides by 360
18=x
answer is 18 degres

And your estamated answer would be 1,000.
2+3=5
179=200
200x5
2x5=10
1,000
To figure out your real answer you will have to take 179 and multiply it by 5 so it will look like this:
