Answer 2

Hi friend
--------------
Your answer
---------------------

Inner circumference of a circular path = 44 m

Width of the path = 7 m

Now,
---------

Circumference = 2 × π × r

(2×22×r)/7 = 44

r = (44×7)/2×22

r = 7m

So,
------

Inner radius = 7 m

Outer radius = R = (inner radius + width of the path)

= (7 + 7)m = 14m

Outer circumference = 2×π×R

(2×22×14)/7 m

= 88 m
