$$\blue\textsf{\textbf{\underline{\underline{Question:-}}}}$$

What does the formula 4πr² give?

$$\blue\textsf{\textbf{\underline{\underline{Answer and how to Solve:-}}}}$$

Formula for Volume of a Sphere:-

$$\bold{V=\displaystyle\frac{4}{3} \pi r^3}$$

So the answer is not Option A.

Formula for Surface Area of a Sphere:-

$$\bold{A=4\pi r^2}$$

This looks exactly like the formula we need.

$$\boxed{\boxed{\underline{\bold{Option\:B}}}}$$

Good luck.

b) The surface area

Step-by-step explanation:

Surface area of sphere formula,

→ 4πr²

Thus, option (b) is the answer.
