1. Measuring Angles

Convert each degree measure to radians. Leave answers as multiples of π. See Examples 1(a) and 1(b). ―1800°

Convert each radian measure to degrees. See Examples 2(a) and 2(b). ―8π/5

In Exercises 71–74, find the length of the arc on a circle of radius r intercepted by a central angle θ. Express arc length in terms of 𝜋. Then round your answer to two decimal places.Radius, r: 12 inchesCentral Angle, θ: θ = 45°
