Question

Bhuvanesh builds a circular lawn of radius 28 m. in front of his house. A path of 7 m. width is laid around outside the lawn. Find the area of the circular path.

Answer 1

Radius of circular lawn r = 28 m 

Area of inner circle = πr2

= 2464 sq.m 

A path laid outside the lawn.

Width of the path = 7 m. 

Radius of the outer circle 

= Inner radius + width of path 

= 28 + 7 = 35 m 

Area of the outer circle = πr2

= 3850 sq.m.
