Given,
The radius of the sphere is
[tex]r=7\text{ cm}[/tex]
The surface area of the sphere is
[tex]SA\text{ = 4}\times\frac{22}{7}\times r^2[/tex]
Solution,
Calculate the surface area of the sphere is
[tex]\begin{gathered} SA\text{ = 4}\times\frac{22}{7}\times\lparen7\text{ cm\rparen}^2 \\ SA\text{ = 4}\times22\times7 \\ SA\text{ = 616 cm}^2 \end{gathered}[/tex]
Thus, the surface area of the sphere is 616 sq. cm.
Therefore, the given option (c) is correct.
