WebEasier Version For Angles. We just saw how to find an angle when we know three sides. It took quite a few steps, so it is easier to use the "direct" formula (which is just a rearrangement of the c 2 = a 2 + b 2 − 2ab cos(C) formula). It can be in either of these forms: cos(C) = a 2 + b 2 − c 2 2ab. cos(A) = b 2 + c 2 − a 2 2bc. cos(B) = c ... WebMar 29, 2024 · 4. Multiply the radius by the arc’s central angle. The product gives you the length of the arc. For example: arc length = 2.36 ( 10) = 23.6 {\displaystyle {\text {arc length}}=2.36 (10)=23.6} So, the length of an arc of a circle with a radius of 10 cm and a central angle of 23.6 radians, is about 23.6 cm.
