If you know the diameter, simply multiply diameter x pi.If you know the radius, multiply radius x 2 x pi.
The circumference is: 6*pi/pi = 6 units
Since circumference equals pi times the diameter, if the diameter of a circle is 6, then its circumference is going to be pi times 6 or 6 pi.
Circumference of a circle: 2*pi*radius or diameter*pi
Circumference of a circle = 2*pi*radius or pi*diameter
The circumference of the circle: 6*pi meters
The circumference of a circle is 2*pi*r. With r = 3, the circumference is 6 pi.
Circumference in inches = pi*6 or 2*pi*3
Circumference = 2*pi*3 or 6*pi
Circumference of a circle: 2*pi*radius or pi*diameter
Circumference of circle: 6*pi inches
Circumference of circle: 6*pi inches
Circumference = pi D = 6 pi = 18.85 ft(rounded)
