Question

The circumference of a circular garden is 256 cm, then a 14-km car road is built next to the garden. Preeti Find the area of ​​our area 8.​

Answer 1

Answer:

Circumference =

Since we are given that  the circumference of the outer circle is 110 m

So,  

Where r is the radius of outer circle .

Thus the outer radius is 17.5 m

Now we are also given that circumference of the the inner circle is 88 m .

So,  

Thus the inner radius is 14 m.

Width of road = Outer radius - inner radius

                       = 17.5 - 14

                       = 3.5 m

Thus the width of the road is 3.5 m
