The cylinder and the cone have the same volume. What is the height of the cone?

The general principle is: for a fixed 'base' (any shape) and a fixed height, the cone (joining everything on the base to one point at that height) is 1/3 the volume of the cylinder of the same height.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
