Answer:
Step-by-step explanation:
this is two circles, one inside the other, circles have an area of pi*[tex]r^{2}[/tex] the flower bed is 20 meters in diameter or 10 meters in radius.
flower bed Area = 3.14*[tex]10^{2}[/tex]
flower bed Area = 314 [tex]m^{2}[/tex]
circle of sidewalk adds 3 meters
sidewalk circle area = 3.14*[tex]13^{2}[/tex]
sidewalk circle area = 530.66
subtract the flower bed area from the sidewalk area, and you have just the walk way it self.
530.66 - 314 = 216.66 [tex]m^{2}[/tex] for the sidewalk only
