An easy to use online calculator to calculate the arc length s the length d of the Chord and the area A of a sector given its radius and its central angle t. You can find the arc length of a curve with an integral that looks something like this. It is a measure of the height of the arc.
The length of the chord sagitta and radius of the arc are inter-related and if you know any two you can calculate the third.
The formula to calculate the arc length is. Then if you multiply the length all the way around the circle the circles circumference by that fraction you get the length along the arc. Plugging our radius of 3 into the formula we get C 6p meters or approximately 188495559 m.
