Question

a road which is 7 M wide surrounds a circular Park whose circumference is 352 M find the area of road.

Answer 1

circumference=2 (l+b)
352=2 (l+7)
176=l+7
176-7=l
l=169M
arae=l×b
=7×169
=1183Msquare

Answer 2

circumference of circle =
$2\pi r$
so we have the circumference so we would do it opposite to find diameter
=
$2 \div \frac{7}{22} | 352$

do whatever
