Once you've found the central angle, you can plug it into the circumference formula from earlier to create and arc length formula. To obtain the arc length formula for degrees, take your central angle value, divide it by 360 and then multiply the result by our circumference formula. Arc L...
Arc length formula: \(l=(nπr)/180\) or \(l=n/180·πr\) or \(l=|α|r\) n is the number of center angles,r is the radius, *α is the central angle of the arc. In a circle with a radius R, since the arc length of the 360° center angle is equal to the circumferenc...

IT IS CONVENTIONAL to let the letter s symbolize the length of an arc, which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally, "stretches under."The circumference of a circle is an arc length. And the ratio of the circumference to the diameter ...
