    The bead is in a cylindrical shape and the formula for solving the volume of a cylinder is V=pi*r²*h where "r" is the radius, "h" for the height.

    We have given values such as:

    r=diameter/2 = 2/2 = 1mm

    h = 8mm

    Solving for the volume, we have:

    V=3.14*1²*8

    V=24.12 mm²
