Afunnel has a diameter of 9 in. and is 16 in. tall a plug is put at the open end of the funnel what it the volume of the cone

The volume of the cone by definition is given by:
 V = (pi * r ^ 2 * h) / 3
 Where,
 h: height
 r: radio
 Substituting the values we have:
 V = (pi * (9/2) ^ 2 * (16)) / 3
 V = 339.2920066 in ^ 3
 Rounding:
 V = 339.3 in ^ 3
 
 the volume of the cone is:
 V = 339.3 in ^ 3

Dbc if u do the math and stuff that what i got let me know if i was wrong
