Hello !
The Area of the ground = 22176 m² 
Area of the circle = πr² 
⇒ πr² = 22176
⇒ r² = 22176 × 7/22
⇒ r² = 1008×7 = 7056 m²
⇒ r = √ 7056
radius = 84 m                  Ans.
Perimeter = 2πr = 2
× 22/7 × 84 = 508 metre
Cost = 508 / 50 = Rs   10.16
Hence the cost for building the fence is Rs  10.16
I hope th4 answer is correct !
Please mark this answer as the best !
