A 22.5 m high tent is in the shape of a frustum of a cone surmounted by a hemisphere. If the diameters of the upper and the lower circular ends of the frustum are 21 m and 39 m, respectively, then find the area of the cloth (in m2) used to make the tent (ignoring the wastage). $\left(Use~\pi=\frac{22}{7}\right)$
