The Side of Square plots 25 m.A circular flower bed at the center has a redius 7 cm and a lawn of 1 m width along its sides . Find the remaining area of the plot. Also Find area of 1m paths around the central circular flower bed ??

Given :-

To find Remaining area and area of Path .

Answer :-

Remaining area = 423.86

Area of Path = 47.14

To Find :-

Area of circle =

$\frac{22}{7*r*r}$

$\frac{22}{7*7*7} = \: 154$

Area with Lawn =

$\frac{22}{7*8*8}$

= 201..14.

Area remaining = Area of Square - Area of circle with lawn .

= 625 - 201.14

423.86

Area of lawn = 201.14 - 154 = 47.14.
