Question

the cost of fencing a circular field at the rate Rs50 per meter is Rs 34,100 . find its diameter and perimeter ​

Answer 1

Answer:

Diameter = 217 m

Perimeter = 682m

Step-by-step explanation:

cost of fencing a circular field = perimeter × cost/m

34100= 2πr×50

34100= 2×22/7×50 × r

r = 34100 ×7/2×50×22

r = 31×7/2

= 217/2 m

d = 2r

= 2×217/2

= 217m

perimeter = 2πr

= 2×22/7×217/2

= 682m
