Find the Circumference circle (6cm)

The circumference of a circle is equal to Pi π times the diameter d.
Since the diameter d is equal to 2 times the radius r, the formula for circumference using radius is 2πr.
Substitute the value of the radius r=6 into the formula for the area of a circle. Pi π is approximately equal to 3.14.
Multiply 6 by 2.
