Question

What is the formula for the volume of a sphere?

• A. $V=3\pi r$
• B. $V=\frac{4}{3}\pi r^3$
• C. $V=2\pi r^2$
• D. $V=\frac{2}{3}\pi r^2$

Answer 1

The correct option is B $V=\frac{4}{3}\pi r^3$

The formula for the volume of a sphere is
$V=\frac{4}{3}\pi r^3$
where, $r$ is the radius of the sphere.
