The curved surface area of a sphere is 5544 sq.cm. Its volume is :

Answer: Option C

$$\begin{array}{rl}& 4\pi r^2=5544\\ & \Rightarrow r^2=\left(5544\times \frac{1}{4}\times \frac{7}{22}\right)\\ & \Rightarrow r^2=441\\ & \Rightarrow r=21\end{array}$$
∴ Volume :
$$\begin{array}{rl}& =\left(\frac{4}{3}\times \frac{22}{7}\times 21\times 21\times 21\right)\text{ c}{\text{m}}^3\\ & =38808\text{ c}{\text{m}}^3\end{array}$$
