Sorry; I don't know how to draw a good diagram....

Consider the circular cross section of the cylinder with center O and the level of the water indicated by segment AB. Let P be on AB such that OP is perpendicular to AB.

Because OP=3 and the radius of the cylinder is 6, triangle AOB is composed of two congruent 30-60-90 right triangles.

Find the area of the cross section of the water as
(1) total area of the circular cross section; minus
(2) the area of the sector AOB; plus
(3) the area of triangle AOB

Then multiply that area by the 24-inch length of the cylinder to get the volume of water.
