Answer 2

The area of road is 2310 sq.m.

Step-by-step explanation:

Radius of circular park r = 49 m

We are given that A 7m road run along a circular park of radius 49m

Width of road = 7 m

Outer radius = 49+7=56 m

Area of road = Outer area - Inner area

Area of road =$\pi R^2 - \pi r^2$

Area of road =$\frac{22}{7} (56^2-49^2)$

Area of road =2310 m^2

Hence The area of road is 2310 sq.m.
