Explanation:

A cinder cone is basically a sharp conical hill which consist of a loose pyroclastic fragments that are being formed on the sides on volcanic vent.

Simply think of a steep volcano and how it acts when it blats out, this is what cinder cone is. When the lava is blown out in a very violent manner, it breaks in to very small particles that can be addressed as cinder. Almost all the cinder cones are made up of pyroclastic substance.
