Question

A circular grass lawn of 35 metres in radius has a path 7 metres wide running around it on the outside. Find the area of the path.

Answer 1

The area of the path is 1694 sq.m.

Step-by-step explanation:

Radius of circular grass lawn r = 35 m

Width of path = 7 m

Outer radius R = 35+7=42 m

Area of path = Outer Area - Inner Area

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

Area of path =$\frac{22}{7}(42^2-35^2)$

Area of path =$1694 m^2$

Hence the area of the path is 1694 sq.m.

Answer 2

Step-by-step explanation:

Radius of circular grass lawn r = 35 m

Width of path = 7 m

Outer radius R = 35+7=42 m

Area of path = Outer Area - Inner Area

Area of path =\pi R^2 - \pi r^2πR
