Question

A Circular pond is of diameter 28m is surrounded by a path of im . wide. Find the area of path.​

Answer 1

Area of the pond = $\pi r^{2}$

= 22/7 x 14 x 14

= 22 x 2 x 14

= 44 x 14

= 616$m^{2}$

Width of the path = 7m

Diameter of the pond including the path = 35

Radius of the pond including the path = 35/2

Area of the of the pond including the path = $\pi r^{2}$

= 22/7 x 35/2 x 35/2

= 962.5$m^{2}$

Area of the path = 962.5$m^{2}$ - 616$m^{2}$

= 346.5$m^{2}$
