Question

the diameter of a circular park is 140m. around it on the outside, a path having the width of 7 m is constructed, if the path has to be fenced from inside and outside at the rate of Rs 7 per meter, find its total cost

Answer 1

Answer:

Rs.6468

Step-by-step explanation:

For inside distance :

Radius = 70 m

Circumference = 2πr = 440 m

For outside distance :

Radius = 70+7=77 m

Circumference = 2πr = 484 m

Total length = 440+484=924 m

Cost = Rs.7×924=Rs.6468
