Question

To fence a circular garden the total cost is 26400 at the cost of 50 rupees per metre find the radius of the circle

Answer 1

Total cost of fencing = Rs. 26,400

cost of fencing = Rs.50 per meter

Total length of fence = 26,400/50 = 528m

Thus perimeter of circular garden = 528 m

If the radius is R

2πR = 528

⇒R = 528/2π

⇒R = (528×7)/(2×22) 

⇒R = 84 m
