Question 817203: a circular ground of radius 7 m has a path of width 7 m around it on its outside. the area of path is approximately equal to ?

You can put this solution on YOUR website!
Radius of path + circular ground = 14m
(area of ground + path) - (area of ground)
(Pi * 14^2) - ( Pi * 7^2)
615.75 - 153.94
= 461.8 m^2 (the area of the path)
Hope this helps.
