The shape of the shell resembles a cone with an approximate diameter of 21 mm and an approximate height of 38 mm.

What is the approximate volume of the shell? (Use 3.14 for .)

  • math -

    r=radius=21/2=10.5 mm
    h=height=38mm
    V is in mm³
    Volume of a cone, V
    = (1/3)πr²h
    =(1/3)*3.14*10.5²&38 mm³
    =4385 mm³
