Pi times the diameter of a circle gives its circumference. Since the radius is 5 cm, the diameter is 10 cm, and pi x 10 cm is the answer, or 31.4159 cm.
Radias
12pi or about 37.699
A circle has one curved line and it is its circumference
Divide the circumference by Pi.
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
Well the radius is only half of the line on the circle the circumference is all around
If you have only the diameter to get the circumference you have to multiply the circumference by pi: 3.14
A circle has only one side and it is its circumference
Radius = circumference/pi
The circumference of EVERY circle is (pi) times (the diameter).Now you can calculate the circumference of not only that particular circle, butalso the circumference of any other circle that you'll ever meet in the future.
perimeter or circumference The only answer is perimeter. The circumference is the the perimeter of a circle; the distance around a circle.
