Answer:
Let radius of Area (A)= Radius of circular park +radius of road
=12+4=16 cm
Using Area of Circle= pi.r²
A=pi×16²
=pi×256
Area of circular Park(a)=pi*12²
=pi*144
Now Area of Circular Road= A-a
=pi.*256-pi*144
=pi(256-144)
=pi(112)
=2464/7
=352 cm²
Area of the road= 352 cm²
Hope this helps you
