What does the formula 4πr² give?
[tex]\blue\textsf{\textbf{\underline{\underline{Answer and how to Solve:-}}}}[/tex]
Formula for Volume of a Sphere:-
[tex]\bold{V=\displaystyle\frac{4}{3} \pi r^3}[/tex]
So the answer is not Option A.
Formula for Surface Area of a Sphere:-
[tex]\bold{A=4\pi r^2}[/tex]
This looks exactly like the formula we need.
So the right answer is
[tex]\boxed{\boxed{\underline{\bold{Option\:B}}}}[/tex]
