If a circle is inscribed in a square with a perimeter of 24 cm, what is the circumference of the circle? The diameter of the circle is 6 cm.

If you only know the diameter you will use this formula:
Circumference= pi x the diameter.
Pi is always 3.14
So you here is what your formula will look like:
unknown circumference = 3.14 x 6
So, unknown circumference = 18.84 cm.
If you go to the website I have given as my source, scroll down a little bit and look at Example 2.

Circumference = D*pi= 6*pi=18.85cm

The circumference of a circle is C = d*pi, where d is diameter and pi is 3.14159. You have d, so you can calculate C with simple arithmetic.

Its circumference is 2pi*3 = 6pi cm.
