\sf \huge \color{Green}{\underbrace{Answer} }:

Surface area = 1386cm²

Volume = 4851cm³

\sf \huge \color{Green}{\underbrace{Solution} }:

Radius = \frac{21}{2} cm

\large \color{red} \boxed{\sf Surface \: area \:  of \: sphere  = 4πr² } \\ \\ = 4×\frac{22}{7} × \frac{21}{2} ×\frac{21}{2} \\ \\ \sf \implies  \boxed{1386cm²}

\large \color{red} \boxed{\sf Volume \:  of \: sphere  = \frac{4}{3}πr³ } \\ \\ = \frac{4}{3} × \frac{22}{7} × \frac{21}{2} × \frac{21}{2} × \frac{21}{2} \\ \\ \implies \boxed{4851cm³}
