Calculating a circle's arc length, central angle, and circumference are not just tasks, but essential skills for geometry, trigonometry and beyond. The arc length is the measure of a given section of a circle's circumference; a central angle has a vertex at the center of the circle and th...
you find the fraction of the circle’scircumferencethat the arc makes up. Then, if you multiply the length all the way around the circle (the circle’s circumference) by that fraction, you get the length along the arc. So finally, here’s the formula you’ve been waiting...

seen that to add a lot of little bits together is precisely what is called integration, so that it is likely that, since we know how to integrate, we can find also the length of an arc on any curve, provided that the equation of the curve is such that it lends itself to integration...
To find the area of a circle, you take pi times the radius squared, or A = pi r^2. Using this formula, you can find the area of a circle if you know the radius -- or the diameter -- by plugging in your values and solving for A. Pi is approximated as 3.14. ...
The circumference of a circle is found by using the formula 2 * 3.14r or 3.14d. To find the length of an arc, multiply the circle's circumference by the arc's angle, then divide by 360 (arc angle / 360). Arc length = (arc length * (3.14d) / 360 or (arc length * 2 * 3.14...
