WebAnd it works out for every ratio. a tenth of the circumference will have a tenth of the angle. 1/pi of the circumference will have 1/pi of the angle. Now, for this, the circumference is 2pir by defenition And the angle is 2 radians. Of course the full angle all the way around is 2pi. So if we call the arc length S that gives us S/ (2pir) = 2/2pi. WebIt stands for the ratio between the circumference of any circle and its diameter, and it's true for all circles. This means that any circle’s circumference will be about 3.14 times the length of its diameter. Circumference Equation Example. What is the circumference of a circle whose radius is 24 inches?
