4 times pi. That is about 12.57.
diametre of circle
pi * diameter
The circumference of a 34mm circle is: 107 mm
The circumference of this circle is about 14.45 units.
A circle has the radius of 27.7 cm what is the approximate circumference of the circle? The circumference is approx. 174 centimeters.
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
A circumference of 12.57 cm
Circumference = pi x diameter therefore - Diameter = Circumference/pi
It is: 2 to 3 respectively
d = 11.46 inches
circumference of the circle = 4*pi cm
The formula for the circumference of a circle is C = πd, π = 3.142, d = 4cm C = 3.142 x 4cm C = 12.568cm
