Question

What is the volume of the hemisphere whose radius is r?

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

Answer 1

The correct option is C $\frac{2}{3}\pi r^3$

The volume of a sphere whose radius is r is $\frac{4}{3}\pi r^3$

The volume of the hemisphere whose radius is r is $\frac{2}{3}\pi r^3$
