i don't know because the shaded part is not part of the sectors... r=sqrt(360*area of sector/60pi) ?

area of a sector is 60*r^2*pi/360

i know r is half the side i don't get how to relate this all together because the shaded part is not part of the circles...the area of the shaded part is 24. the area of a sector is (24-area of the triangle)/3...

what n?? i don't get it... no, i know the angle of the sectors...i do NOT know the radius that is what i have to find...so i don't know the area of the sectors either

what is left are the sectors of the circles and if u make each one=x then 3x+24=A of the triangle. the arc length is r(2*pi*central angle/360) i don't think that gives any useful information though...except maybe help prove the answer once i find it...
