This question assumes a cell is shaped like a cylinder, with a height of 2 micrometers (um) and circular ends that have a diameter of 1 um.
The volume of a cylinder is equal to adding up the areas of all the circles that you can slice the cylinder into. So you find the area of the circular ends and multiply that by the height of the cylinder. In other words, volume V = area of the circle * height = pi*(radius)^2 * h.
The radius is half the diameter, so the area of the circle is pi*(diameter/2)^2. Now our volume equation is
V = pi*(diameter/2)^2 * h
with the answer given in units of cubic micrometers, or um^3.

Maybe, Pi(r squared) X 2
= approx. 1.57cu. micrometers ?
Hey, I'm just a bio. person, ask again in the mathematics section.
