diameter = 24
radius = 24/2 = 12

area of circular park = 3.14 * 12 = 37.68

12-3=9
area of circular path = area of park - area of inner circle

area of inner circle = 3.14 * 9 = 28.26

So, 37.68 - 28.26 = 9.42 (area of path)



cost of paving path = 25 rupees per meter square 
So, 9.42 * 25 = 235.5 rupees
