Formula for the circumference of a circle = 2 • pi • radius

If diameter = 20cm

20cm divided by 2 = 10cm

The radius of the circle is 10cm, the radius is 1/2 of the diameter and is what we need to calculate the circumference.

2 • pi • 10cm = 62.8 (ROUNDED TO TENTHS PLACE)

The circumference of the circle is 62.8cm squared.
The circumference of the circle is 62.8cm squared.
