A conical vessel without a bottom tightly stands on a table. A liquid is poured into the vessel and as soon as its level reaches a height h. The pressure the liquid raises the vessel. The radius of the bottom greater base of the vessel is R, the semi- vertex angel of the cone is, prop and the weight of the vessel is W. What is the density of the liquid ?

Answer»

`(W)/(pi GH^(2)TAN^(2) PROP (R+(1)/(3) H tan prop ))`
`(W)/(pi gh^(2)tan prop (R+(1)/(3) h tan prop ))`
`(W)/(pi gh^(2)tan prop (R-(h tan prop )/(3) h tan prop ))`
`(W)/(pi gh^(2)tan prop (R-(1)/(3) tan prop ))`
