A circular garden with a radius of 20 meters is surrounded by a walkway that measures 1 meter in width. -1 m 20 m Find the area
juin [17]
<h3>Answer:  128.74  square meters</h3>

=========================================================

Explanation:

The area of the garden only (ignore the circular pathway) is approximately

A = pi*r^2

A = 3.14*20^2

A = 1256

The area of the garden plus the path is approximately

A = pi*r^2

A = 3.14*21^2

A = 1384.74

Notie how I added on 1 meter to increase the radius to 21

Subtract the two circle areas to get the area of the circular ring.

1384.74 - 1256 = 128.74

The units for all of the areas mentioned are "square meters".
