360 angle means 2pi r is length of arc
so for 60 angle the length of arc is pi  r/3 which is equal to 37.4 so
if we do this calculation we get r as some thing which is the answer

Area of sector=lr/2,
wher, l=length of arc and r= radius of circle
Area of sector=(x°/360°)*π
where x°=angle made by the two radii with centre of the circle
i.e; lr/2=(x°/360°)π
      l/2=(x°/360°)πr
     37.4/2=(60/360)*(22/7)r 
     18.7=(1/6)(22/7)r
     18.7*6*7/22=r
      785.4/22=r
     r=35.7cm
Therefore radius of the circle is 35.7cm
