Question

Find the cost of fencing a well of radius 1.54m at the rate of ₹75per meter​

Answer 1

Answer:

Given:- radius of well is 1.54m, rate is ₹75/m

Step-by-step explanation:

for finding cost we have to calculate circumference and multiply it with rate.

therefore, circumference= 2πr

2×π×1.54m

9.68m (if π = 22/7)

now, cost= circumference×rate

9.68m × ₹75/m

₹726

therefore, total cost is 726
