Question

What is the volume of a hemisphere with a radius of 9.7 cm, rounded to the nearest tenth of a cubic centimeter?

Answer 1

Answer:

The volume of the hemisphere is approximately 1911.5 cubic centimeters.

Step-by-step explanation:

The volume of a hemisphere ($V$), in cubic centimeters, is equivalent to the half of the volume of a sphere, that is:

$V = \frac{2\pi}{3}\cdot R^{3}$ (1)

Where $R$ is the radius of the hemisphere, in centimeters.

If we know that $R = 9.7\,cm$, then the volume of the hemisphere is:

$V = \frac{2\pi}{3}\cdot R^{3}$

$V = \frac{2\pi}{3}\cdot (9.7\,cm)^{3}$

$V \approx 1911.498\,cm^{3}$

The volume of the hemisphere is approximately 1911.5 cubic centimeters.
