Question

In the cylinder below, the radius, r, is 5 m, and the volume is 200 m3. What is the altitude of the cylinder?


A.
4 m
B.
13 m
C.
16 m
D.
8 m

Answer 1

Answer:

D, 8 (I think)

Step-by-step explanation:

The formula for the volume of a cylinder is \pi r^2 h. Since you know the volume and the radius, you can set up the following formula:

$200=\pi \cdot 5^2 \cdot h$

$h=\frac{8}{\pi}\approx 2.54$. I know that is not one of the answer options, maybe the pi's didn't render here, and the answer is 8.Anyways, hope this helps!
