    I can't determine the shape, from the image alone. The bottom part may be a right circular cylinder, but the sides do not appear parallel to me, so I'm not sure.

    Please follow the forum guidelines. Thank you!

    As stated above, the sides don't look parallel.
    But if they are parallel, the volume = volume of a cylinder + half the volume of a sphere.
    The radius r = 3cm.
    Radius r = diameter d/2.
    Height h = 10cm.
    Volume of a cylinder = πr2 * h. Where h = height
    Volume of a sphere " (4/3) * πr3.

    So volume of shape = volume of cylinder + [ (1/2) * volume of sphere]
    Because half the sphere is inside the cylinder so we don't want to count that twice
