Question

the circumference of a given circular Park is 55 M it is surrounded by a path of uniform with 3.5 M find the area of the path

Answer 1

circumference =2.22/7.r
55=2.22/7.r
55.7/2.22=r

Answer 2

C=2pie r
55=2*22/7*r
55*7/44=r
8.75=r
Then let small r be =8.75

Outer circumference =8.75+3.5=12.25mtr
Then let capital R be = 12.25

A=pie(R-r)
=22/7(12.25-8.75)
=(22/7)×3.5
=11

Area of path =11mtr.
