To solve for the volume of an oblique cone, you use the formula for the volume of a cone, which is:
\[ V = \frac{1}{3} \pi r^2 h \]
where \( r \) is the radius of the base and \( h \) is the altitude (height) of the cone perpendicular to the base.
Therefore, the correct segments to substitute into the volume formula are:
altitude and radius
