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]

Good luck.
