A.15.75π cm3
B. 17.25π cm3
C. 16.33π cm3
D. 12.5π cm3

Best ResponseYou've already chosen the best response.0I am assuming that the cone's tip ( the cone that the partial cone would be a part of) will coincide with the bottom of the cylinder volume when filled = volume of the cone + 2/3 volume of the cylinder 16.59375 pi = (1/3) pi (3)^2 * (h+ 4) + (2/3) pi (0.,75)^2 h where h is the height of the cylinder

Best ResponseYou've already chosen the best response.03( h + 4) pi + 0.375 pi h = 16.59375pi 3hpi + 12 pi + 0.375 pi h = 16.59375 pi 3h + 12 + 0.375h = 16.59375 h = (16.59375  12) / 3.375 h = 1.3611

Best ResponseYou've already chosen the best response.0the volume of the cylinder = pi * (0.75)^2 * 1.3611 volume of partial cone = 16.59375  volume of cylinder
