Question

A circular path around a circular Park .circumference of circular park is the 110 m and circular path is 220 m find the width of the path also find the area of the park

Answer 1

c=110

$2\pi \: r$

2pi r =110

2*22/7* r = 110

r=110*7/22*2

r=770/44

17.5

a =

$\pi \: r ^{2}$

=22/7*17.5*17.5

=962.5

c=220

r=35

width of path is 35-17.5 =17.5m

the area of park is 962.5 m
