How To Find Arc Length? A Quick Guide For Technical Drawing And Engineering Drawing

An arc of radius = 95mm is passing through points A and B. AB = 87mm. Copy the given figure. Find the length of the given arc by Geometrical construction.
Construction: 11
1. Copy the given figure.
2. Draw a tangent to the arc at A (refer construction 19). Draw the chord AB and produce it beyond A to a point P such that AP = ½ AB. With center P and radius equal to PB, describe an arc cutting the tangent at C.
3. Then the length AC is approximately equal to the length of the arc AB.
