$\large{ \sf \underline{ \blue{ ╬ \: question \: ╬}}}$

5.The surface area of a sphere of radius 14 cm is:

$\large{ \sf \underline{ \blue{ ╬ \: given \: ╬}}}$

Radius =?

$</p><p>\large{ \sf \underline{ \blue{ ╬ \: find \: ╬}}} </p><p></p><p>$

Total surface area of sphere

$\large{ \sf \underline{ \blue{ ╬ \: formula \: used \: ╬}}}$

Total surface area of sphere= 4πr^2

$</p><p> \large{ \sf \underline{ \pink{ ╬ \: solution\: ╬}}} </p><p></p><p>$

$\bf\implies Given \: radius \: of sphere \: = \: 14cm^2 \\ </p><p> \bf\implies surface \: area \: of sphere \: = \: 4πr \\ </p><p></p><p> </p><p> \bf\implies =4×3.14×(14) ^2 \\ </p><p></p><p> </p><p> \bf\implies surface \: area \: of \: sphere = 2461.76cm^2</p><p></p><p> .$

Therefore 2461.76cm^2 is your answer.
