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 $$m^{2}$$) used to make the tent (ignoring the wastage).
(Use $$\pi = \frac{22}{7}$$)

A

$$2800\frac{2}{7}$$

B

$$787\frac{2}{7}$$

C

$$1635\frac{6}{7}$$

D

$$2107\frac{2}{7}$$
