(pi)r^2h = 121
Hence h = 121/(pi)r^2 (Answer).
Further, substituting 22/7 for "pi" gives,
h = (121 x 7)/22 x r^2
= (11 x 11 x 7) / 11 x 2 x r^2
=77 / 2r^2
=77 x 2^-1 x r ^-2 (Just for extra knowledge).

A cylinder is just a 2-dimensional circle extended into the 3rd dimension, a circle with height if you will.
The area of a circle = pi x radius x radius
The volume of a cylinder = the area of the circle x height

V=d2pi/4 xh is equation to calculate volume of cilinder. The volume of ciliner depends on diameter and height. So it is the function of diameter and height. The "pi " number is the constant.

Cylinder
Volume Formula
V = π r² h
π r² and h are directly proportioinal to volume.
