$\underline{SOLUTION}$ ➡

$Given ,\\ \\ Diameter \: \: of \: \: the \: \: sphere \: = 14 \: \: cm \\ \\ So ,\\ \\ Radius \: \: of \: \: the \: \: sphere \: ,r = \frac{14}{2} \: \: cm = 7 \: cm$

$We \: \: know \: \: that,\: \\ \\ Surface \: \: area \: \: of \: \: a\: \: sphere = 4\pi \: r {}^{2} \\ \\ = (4 \times \frac{22}{7} \times (7) {}^{2} \: ) \: \: cm {}^{2} \\ \\ = (4 \times \frac{22}{7} \times 49) \: cm {}^{2} \\ \\ = (4 \times 22 \times 7) \: \: cm {}^{2} \\ \\ = 616 \: \: cm {}^{2}$
