[quote="tom09b"]If cylinder A has three times the height and one-third the diameter of cylinder B, what is the ratio of the volume of A to the volume of B?

A 3:1

B 1:1

C 1:3

D 1:9

E 1:27

\(Volume_A=\pi{r}^2*h\);

\(Volume_B=\pi{(3r)}^2*\frac{h}{3}=3\pi{r}^2*h\);

Ratio 1:3.

Answer: C.

Pay attention Bunuel

The question states that the cylinder A has 3 times the height and 1/3 the

DIAMETER of cylinder B

It means that 1/3 DIAMETER= 2/3 RADIUS !!!!!

DIAMETER= 2*RADIUS

The question implies that cylinder A has three times the height than the height of B and cylinder A has one-third the diameter than the diameter of B.[/quote]

What does it mean "one-third the diameter"???

It implies that 2/3 the radius.

Volume's formula use radius not diameter
