Answer 2

Given info : There is a fountain in the centre of a circular park. The distance of the fountain from the boundary of the park is 70 m.

To find : The total cost of fencing the park if the rate of fencing is 350 $ per metre.

solution : circumference of park = 2πr

here r = distance of the fountain from the boundary of the park = 70m

so circumference of park = 2 × 3.142 × 70

= 140 × 3.142 m

= 439.88 m

now total cost = circumference of park × rate of fencing

= 439.88 × 350

= 153958 $
