I know what it is, but I don't know how to explain it that well. Is that okay for you?

Well, using the formula for volume of the cylinder

4. anonymous

Ok, just figure out the volumes of the two and then compare. The volume of a cylinder is $\large V=\pi*r^{2}*h$

5. MichaelAlex292

V = (pi) (r ^2) (h)

6. MichaelAlex292

cylinder a is 4pi, while cylinder b is 8pi

Πr^2h1/Πr^2h2 =h1/h2

8. MichaelAlex292

Therefore the ratio is 1/2, or 1:2

Ahh thank you!

No problem
