Example Questions

Example Question #11 : Cavalieri's Principle: Ccss.Math.Content.Hsg Gmd.A.2

Find the volume of a hemisphere with radius \(\displaystyle 341\). Round your answer to the nearest hundredth.


Possible Answers:

\(\displaystyle 83046579.7\)

\(\displaystyle 166093159.41\)

\(\displaystyle 52869094.67\)

\(\displaystyle 26434547.33\)

\(\displaystyle 39651821\)

Correct answer:

\(\displaystyle 83046579.7\)

Explanation:

In order to find the volume of a hemisphere, we need to recall the volume of a hemisphere equation.

\(\displaystyle V = \frac{2 \pi}{3} r^{3}\)

We simply plug in 341 for \(\displaystyle \uptext{r}\).

\(\displaystyle V=\frac{2}{3}\cdot\pi\cdot ( 341 )^3\)

\(\displaystyle V= 83046579.70337164\)

Now we round our answer to the nearest hundredth.

\(\displaystyle V= 83046579.7\)


Example Question #12 : Cavalieri's Principle: Ccss.Math.Content.Hsg Gmd.A.2

Find the volume of a hemisphere with radius \(\displaystyle 7\). Round your answer to the nearest hundredth.

Possible Answers:

\(\displaystyle 1436.76\)

\(\displaystyle 343\)

\(\displaystyle 457.33\)

\(\displaystyle 228.67\)

\(\displaystyle 718.38\)

Correct answer:

\(\displaystyle 718.38\)

Explanation:

In order to find the volume of a hemisphere, we need to recall the volume of a hemisphere equation.

\(\displaystyle V = \frac{2 \pi}{3} r^{3}\)

We simply plug in \(\displaystyle 7\) for \(\displaystyle \uptext{r}\).

\(\displaystyle V=\frac{2}{3}\cdot\pi\cdot ( 7 )^3\)


\(\displaystyle V= 718.3775201208659\)

Now we round our answer to the nearest hundredth.

\(\displaystyle V= 718.38\)
