Question

A 5 m wide path is to be constructed all around, and outside a circular garden of diameter 112 m, Find the cost of
constructing the path at 45 per square metre.

Answer 1

Answer:

Step-by-step explanation:

diameter = 112m

so, radius = 112/2

                 = 56m

area = πr²

22/7*56²= 9855.82m²

Now, new diameter = 117m so, radius = 58.5m

area = 10755.45m ²

area of path = 10755.45 - 9855.82

                     =900m²

cost of construction @ 45 = 45 * 900

                                           = Rs. 40,500
