If you have a cone that is 15 in and slant height 14 inches in height and 12 in in radius what's your answer

Unfortunately, the given measurements are inconsistent.

A cone cannot have a radius of 12 inches and a slant height of 14 inches while also having a height of 15 inches.

The slant height of a cone must always be longer than the radius, and the height must be shorter than the slant height. Therefore, the given measurements are not possible for a cone.
