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
You can't multiply anything to get a prime number ?

sin(4(3.141593^3)+3.141593^4)
sin((4)(31.006277)+3.141593^4)
sin(124.025107+3.1415934)
in(124.025107+97.409091)
sin(221.434198)
=0.998844
Tbh, might be wrong on this one. I'm on the road so didn't double-check my answer.
Area of the square: A s = s².
Area of the circle: A c = ( 1/2 s )² π = 1/4 s² · 3.14 = 0.785 s²
Area inside the square but outside the circle: s² - 0.785 s² = 0.215 s²
The ratio:
0.215 s² : s² = 0.215 : 1 = 215 : 1000 = 43 : 200 .
