Question

a fence is to be erected around a circular field the cost of fencing comes to rs 2640 at the rate of rs 12 per metre find the radius of the circular field

Answer 1

Circumference of the field = 2640/12 = 220 m

2×π×r = 220
⇒ r = 220/(2π) = 35 m

Answer 2

Step-by-step explanation:

Circumference of the field = 2640/12 = 220 m

2×π×r = 220

⇒ r = 220/(2π) = 35 m
