is arc length in radians. Start fraction 3 pi divided by 2 end fraction. And it is here that the term trigonometric function has its full meaning.
Arc Length Formula From Circumference Google Search Formula Arc Circumference from www.pinterest.com
Which gives arc length s. If you are give that the angle is 20 degrees for example then you would assume that the arc length is 20360 or 118 of the circumference thus arc length s would be s 20360 2 pi r 19 pi r. The central angle however does not have to be in radians.
Dfrac 3pi 2 23p.
When the central angle is in degree measure use this formula. The formula is S r th where s represents the arc length S r th represents the central angle in radians and r is the length of the radius. Arc Length Formula - Example 1 Discuss the formula for arc length and use it in a couple of examples. If you are give that the angle is 20 degrees for example then you would assume that the arc length is 20360 or 118 of the circumference thus arc length s would be s 20360 2 pi r 19 pi r.
