1)2*pi*r - r= 37
r(2*pi - 1) =37
r(2*(22/7) -1) = 37
r(44- 7/7)= 37
r(37)= 37*7
r= 7cm
2 * 22/7*7 = 44cm
2) area of 1 circle -area of 2 circle will give the width so 1886.5-1386.0=1491.5
3)area of rectangle-area of circle = l×b=12×5=60m^-2πr=286/7=134/7=19.3
hope it helped if it pl mark as brainlist
