    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
