Question

cost of building a fence around a circular field is rs 7700 at rs 14 per foot.area of circular field???

ans(24062.5) anyone pls help

Answer 1

circumference = 7700/14 ft
= 550 ft

since C = 2πr
2πr = 550
r = 275/π

area = π(275/π)^2
= (275^2)/π
= appr 24072.2 ft^2

I waited to do any calculations to the very end, then used π of my calculator.
