Question

The cost of fencing a circular field at the rate of Rs 24/m is Rs 5280. Find the radius of the
field.

Answer 1

Step-by-step explanation:

Cost of fencing per m=Rs.24

Cost of fencing the field =Rs.5280

Now

Circumference of circle×24=5280

$2\pi \: r \: \times 24 = 5280$

2×3.14×r×24=5280

r=5280/150.72

r=35.03m
