The volume of a cylinder is given by the formula
v = pi (r^2) (h)
We have the volume v (121), and we have the radius r (which is 3. We don't have height. Plug and solve.
121 = pi(3^2)h
121 = pi(9)h
Divide both sides by 9pi, to isolate h.
121/(9pi) = h

V = Pi r squared height. So, r squared = 9. Pi = 3 (ish), so divide 121 by 27. You will be left with height.

Calculate the area of the base. Divide the volume by the area of the base to get the height.

vol A/volB =625/5000 =125/1000 =5^3/10^3 ratio of lengths A/B = 5/10=1/2 10/h =1/2 h=20cm

Cylinder
Volume formula
V = π r² h
v / π r² = h. . .Use this formula
- - - - - - - - - -
121 / 3.141592654(3)² = h
121 / 3,141592654(9) = h
121 / 28.27433388 = h
4.279499581 cm = h
4.3 cm rounded to one decimal place
The answer is: the height is 4.3 cm

V =pi*r^2 *h ===> h= V/pi r^2
h =4.28cm
