Circumference of a circle = 2*pi*radius or diameter*pi
The formula for the circumference of a circle is C = πd, π = 3.142, d = 4cm C = 3.142 x 4cm C = 12.568cm
About 12.56 cm Btw the formula is diameter x pi (3.14)
The circumference of a circle with a radius of 4cm is: 25.13 cm (r x 2 x pi)
It is: 2 to 3 respectively
Circumference of a circle = 2*pi*radius or diameter*pi
A circumference of 12.57 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
About 12.56 cm Btw the formula is diameter x pi (3.14)
The circumference of a circle with a radius of 4cm is: 25.13 cm (r x 2 x pi)
radius=4cm diameter=8cm *radius is half the diameter
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
It is: 2 to 3 respectively
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
