What is the effect of on volume of tripling the dimensions of this cylinder? The radius is 2 and the height is 7.
--------------
If both the radius and the height are tripled, the volume is multiplied by 27.
-------------
The radius is 2 and the height is 7.
That is not relevant. It's x27 for any dimensions.

none of the given responses are correct

V1 = pi * 2^2 * 7 = 28 pi

V2 = pi + 6^2 * 21 = 756 pi

(756 pi) / (28 pi) = 27
