Step-by-step explanation:
I'm assuming you are saying volume?
But I'll do both volume and surface area.
also note that 0.66 is the diameter, not radius
If 3.41946 is the volume:
V of cylinder = pi*r^2*h
3.41946 = pi*0.33^2*h
h = 3.41946/(pi*0.33^2) = 9.99493043 cm
If 3.41946 is the surface area:
SA of cylinder = pi*r*(r+h)
3.41946 = pi*0.33*(0.33+h)
0.33+h = 3.41946/(pi*0.33) = 3.29832704
h = 3.29832704-0.33 = 2.96832704 cm
