  1. you know how to find the area of a circle: A = πr^2

    so, subtract the area of the small circle from that of the large one.

  2. Radius of circular garden=25m
    Radius of inner circle=25-3
    =22m
    Area of garden available to play children in=pie r^2
    =3.14×(22)^2
    =3.14×484
    =1519.760m^2
