2. In a circle of radius R, central angle \alpha intercepts an arc of length \ell. \(\bullet\)a. Find \ell in terms of \alpha and R when \alpha is measured (i) in radians and (ii) in degrees. b. Find the area of the shaded sector in terms of \alpha and R when \alpha is measured (i) in radians and (ii) in degrees.
