You can put this solution on YOUR website! A circular flower bed is 6 meters in diameter and has a circular sidewalk around t 1 meter wide. Find the area of the side walk in square meters.
***
Area of a circle=πr^2, r=radius
radius of flower bed=1/2 diameter=1/2*6=3
Area of flower bed=πr^2=9π
Radius of flower bed with one meter wide sidewalk around it=3+1=4
Area of flower bed with one meter wide sidewalk around it=πr^2=16π
Area of sidewalk=16π-9π=7π≈22 square meters
