The perimeter of a circle with radius r is
given
by Pi *r*r
...(1)
The problem is that the exact value of Pi
is unknown and hence it is impossible to determine the value of the
perimeter.
However, if you agree to approximate the
value of pi (usually taken as 22/7 OR 3.14159), the approximate value of
the perimeter may be calculated by using (1).
