ah i know this is easy but i forgot how to fo it.

Volume of a cine
solve for h: V=1/3pi r^2h

oh ya when it says for h, it means what would the formula be

So you are saying:

Given the relationship of volume, radius and height for a cone, express height as a function of volume and radius.

Is that correct?

V = pi* r^2 * h /3

Divide both sides by pi * r^2 Multiply by 3 and you get
h = (3 * V) / (pi * r^2)

Its interesting how this relates to the formula for the area of a circle. A = pi * r^2.
V = A * h/3

What is it about the location h/3 in a triangular section that makes it suitable for determining the volume when multiplied by the area of the base? Is it the centroid? :) Why might that idea be useful?

well if V=1/3pi r^2h then wouldn't h=3V/pi r^2?

I'm not sure that's possible without the radius. 1.047197551 (rounded)...r^2h. You still need to supply either r or h.

Do you mean a cone well if you do i use a different foumula :
v=PI R squared divided by 3

(3)(v)(pi)= 2h log r
(3v(pi))/(2log(r))=h


its hard to say cuz u wrote ur question wierd ... i solved this equasion--->
v = (1/(3pi))* r^(2h)

h = 3v/ (pie r^2)
