Question: a circular swimming pool has a diameter of 35 metres what is its circumference

Solution:

We know that the perimeter of the circle is known as the circumference.

There is a formula for finding circumference of a circle.

Circumference = 2$\pi$r or $\pi d$

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 = 35 m

Circumference = 2$\pi$r or $\pi d$

= 22/7 * 35

= 22 * 5

= 110 m

So, The circumference is 110m
