Question

A farmer buys a circular field at the rate ₹ 700 per m² for ₹ 316800. Find the perimeter of the field.

Answer 1

Hey friend...!,!

Area of the circular field = 316800/700
= 452.571

So, pi x r square = 452.571429
22/7 x r square = 452.571429
R square = 452.571429 x 7/22
R square = 144
R = 144 under root
R = 12
Therefore, radius = 12 m

So, perimeter = 2 x pi x r
= 2 x 22/7 x 12
= 44/7 x 12
= 75.428

Hope it helps...!!!
