Inner radius ==>
2πr= 330==> r= 52.5
Therefore outer radius = 52.5+10.5= 63
Circumference of outer radius= 2πr
2*22/7*63= 396
So for fencing at 2 rs==>
396*2= 792
2πr= 330==> r= 52.5
Therefore outer radius = 52.5+10.5= 63
Circumference of outer radius= 2πr
2*22/7*63= 396
So for fencing at 2 rs==>
396*2= 792
