Question

What is the cost of fancing a circular garden of radius 35m with four rounds of wire, if wire costs ₹ 44 per metre?

Answer 1

Step-by-step explanation:

radius of garden= 35m

therefore, suface area of sphere =4πr^2

=4x22/7x35

=4x22x5

=440m^2

hence, for fencing the garden with four rounds of wire= 440x4

=1760 m^2

cost of fencing per metre = RS 44

therefore, total fencing cost = 1760x 44

=77,440

therefore, cost of fencing circular garden of radius 35m is Rs 77,440
