diametre of circle
pi * diameter
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
The circumference of a 34mm circle is: 107 mm
The circumference of this circle is about 14.45 units.
2.35
Times the diametre by pi
The circumference of a circle = pi*diametre = 2pi*radius
The circumference of a circle with a radius of 4cm is: 25.13 cm (r x 2 x pi)
Circumference = Pi X Diameter = 3.1415 X 4cm = 12.566cm
Circumference of a circle = 2*pi*radius or diameter*pi
Circumference = pi x diameter therefore - Diameter = Circumference/pi
d = 11.46 inches
A circumference of 12.57 cm
It is: 2 to 3 respectively
circumference of the circle = 4*pi cm
C = 12.6 cm
