The volume V of a cylinder of height H and base radius R is
V = Pi * R^2 * H.
We have R = 3.5 cm = 35 mm, but we don't have H. If H = h mm, then the answer is
V = (1225 Pi h) mm^3.
If instead you meant what is the volume of a sphere of radius 3.5 cm...
The volume V of a sphere of radius R is
V = (4/3) Pi R^3 = (171500 / 3) Pi mm^3.

What's the height of the cylinder?
Volume = area of base x height
V = pi*(3.5^2)(height)
V = (38.48 mm^2)(height mm)
.

v = bi * r ^2 *h
= 22/7 * 3.5 ^ 2 * h
= 22/7 * 12.25 * h
= 38.5h cm3
=3850h mm3 (h is the height in mm)

First of all, volumes are measured in cm cubed or millilitres. Secondly, unless you know how tall it is, you can't answer this question.
