We know that the perimeter of the circle is known as the circumference.
There is a formula for finding circumference of a circle.
Circumference = 27 r or ad
Where r refers to radius and d for diameter.
The longest chord of the circle is diameter and the half of it is radius.
Value of Pi is 3.14 or 22/7
So, Substituting the values of the circular swimming pool.
Diameter = 42m
Circumference = 27 r or Td
= 22/7 * 42
= 22 * 6
= 132 m
So, The circumference is 132m.
