Question

Given a sphere with radius r, the formula 4rr gives

Answer 1

Answer:

b) The surface area

Step-by-step explanation:

Surface area of sphere formula,

→ 4πr²

Thus, option (b) is the answer.

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.

So the right answer is

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

Good luck.
