A circular garden is surrounded by a fence of negligible width along the boundary. If the length of the fence is 1/6 of th area of the garden. What is the radius of the circular garden? Choose the correct choice
A) 1  B) 2  C) 4  D) 8  E) 12

Rationale: "as per the question - - width is negligible now , let l be the length of the fence = 2 pir l = 1 / 6 ( pir ^ 2 ) pir ^ 2 = 12 pir r = 12 answer : e"
Answer: E
