The area of a circular place is 17.56 hectares. Find the cost of fencing it at the rate of Rs. 3/meter approximately. Pick one.
A) Rs. 4233  B) Rs. 4350  C) Rs. 4457  D) Rs. 4670  E) Rs. 4756
Area = (17.56 x 10000) m2= 175600 m2.   ΠR2 = 175600 ⇔ (R)2 = (175600 x (7/22)) ⇔ R = 236.37 m.   Circumference = 2ΠR = (2 x (22/7) x 236.37) m =1485.78 m.   Cost of fencing = Rs. (1485.78 x 3) = Rs. 4457.   Rs. 4457
