You da real mvps. If the measure of the arc or central angle is given in radians then the formula for the arc length of a circle is Arc Length thr where th is the measure of the arc or central angle in radians and r is the radius of the circle. Whenever you want to find the length of an arc of a circle a portion of the circumference you will use the arc length formula.
S 2p r th360 when th is measured in degrees and.
So the arc length between 2 and 3 is 1. If you have the diameter you can also use pd p d where d diameter d d i a m e t e r. L th C 2p. Well need the following derivatives for these computations.
