The arc length formula is s = r*theta, where r is the radius and theta is the central angle in radians (not degrees).
Here, r = 3.4 cm and the central angle is 46 degrees. We MUST convert this measure 46 degrees into radians, using the conversion factor derived from 180 degrees = pi radians:
arc length = r*theta = (3.4 cm)*(46 degrees)*(pi rad) / (180 degrees) =
2.730 cm (to the nearest thousandth)
