Answer» Radius of park = 84/2 = 42m Area of road = π(45.5² - 42²)= 962.5 m² Cost = Area*Rate= 962.5*200= ₹ 192500 Please hit the like button if this helped you but first we have to take out are area off garden and the area off road is 5544m2. then we have to substracte the m2 by the m2 of road Reply sir There are two circles, one is only the garden and the other is garden plus road. The area of the garden plus road is the outer bigger circle. The area of the garden only is the smaller inner circle. The area of the path is the difference between the area of bigger circle and smaller circle. |
