Question

A circular flower bed is 22m in diameter and has a circular sidewalk around it 3m wide. find the area of the sidewalk in square meters.

Answer 1

solution:

Area of circle= pi r^2

Area of circle without side walk= pi*11*11

= 121*pi m^2

Now,area of circle with side walk.

= pi*14*14

= 196 pi m^2

so, Area of side walk

= {pi(196 - 121) }m^2

= 75pi m^2
