A circular garden is surrounded by a fence of negligible width along the boundary. If the length of the fence is 1/5 of th area of the garden. What is the radius of the circular garden?	Select
A) 1  B) 2  C) 10  D) 8  E) 16
as per the question-- width is negligible   now,   let L be the length of the fence =2pir   L=1/5(pir^2)   pir^2=10pir   r=10   Answer : 10
