The circumference of a circle if the diameter is 12cm is 37.7cm

360 / 78.2 = 4.60 - Gives the number of "slices of pie" of this size in the entire circle 4.60 * 12 = 55.245 - Gives circumference of the circle radius = circumference / 2pi radius = 55.245 / 6.283 = 8.79

The radius of a circle with a circumference of 110 is: 17.507

The circumference of a circle with a radius of 6.7 is: 42.097

The circumference of a circle if its radius is 3 is about 18.85

The circumference of a circle is C = 2Ï€r, where C is circumference, Ï€ is pi (3.14), and r is radius. C = 2 x 3.14 x 12cm = 75cm = 75/1 cm

12pi cm

Radius in from the center of circle or sphere, so a radius of 3.8 cm is a diameter of 7.6cm and circumference 23.8 cm (or 24 cm). Or If you mean 3.8 is the diameter (width), then radius is half (1/2) which equals 1.9 cm and circumference of 11.9 cm (12cm). Or If circumference 3.8 then radius is 1.2cm and area is 1.152cm.
