Solution 2 If a circle has radius r, then an arc of α radians has length r α. So with an infinitesimal increment d θ of the angle, the length is the infinitesimal r d θ. And the arc is a right angles to the radius, which changes by the infinitesimal amount d r. So the infinitesimal area involved is just the product r d r d θ.
