Cicumference of 7' circle
WebThe circumference is pi times the diameter if it were opened up and straightened out to a line segment. The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large. WebMar 27, 2024 · Let's look at an example. Suppose you want to find the circumference of a 5 cm diameter circle. These would be the steps to follow: Use the appropriate equation, which, in this case, is the circumference to diameter formula: c = πd.; Input the diameter in the equation: c = π × (5 cm) = 15.708 cm.; That's it.
