Me i'm desperate!

solve v=(1/3)(pi)h^2(3r-h) for r.

(if you want to see the question better, look at the picture)

also, explain how to solve it. (and if you could provide a visual, that would be great.)

i'm sure goog can you get that answer

$12. that is my answer.

step-by-step explanation:

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
