Question

A circular garden is surrounded by a circular path of 7m width.If the area of path is 770m²,find the area of the garden without path.

help me this question ⁉️​

Answer 1

Answer:

Radius of the circular garden

= 210 sq

=105m

Radius of the region covering the garden and the path =105m+7m

=112m

Area of the region between two concentric circles

with radius of outer circle R, and inner circle r =π(R sq−r sq)

Hence, the area of the path

=π(112sq−105 sq)= 7/22

(12544−11025)

= 33418/7

=4774m sq
