Question

the side of a square plot is 25 m.a circular flower bed at the centre has a radius 7m and a lawn of 1m width along its sides. find the remaining area of the plot. also find the area of 1m path around central circular bed.
​

Answer 1

Question

A circular flower bed is surrounded by a path 4m width. The diameter of the flower bed is 66m. What is the area of this path?(Take π=3.14)

Diameter of the circular flower bed=66m

∴ Radius of circular flower bed(r)=266=33m

∴ Radius of circular flower bed with 4 m wide path(R)=33+4=37m

According to the question,

Area of path=Area of bigger circle−Area of smaller circle

=πR2−πr2=π(R2−r2)

=π[(37)2−(33)2]

=3.14[(37+33)(37−33)] [∵a2−b2=(a+b)(a−b)]

=3.14×70×4

=879.20m2.

Therefore, the area of the path is 879.20m2.
