The correct type of cylinder depends on the specific characteristics of the shape in question.
- If the cylinder's sides are not perpendicular to the base and the bases are circular, it is an oblique circular cylinder.
- If the cylinder has its sides perpendicular to the base and the bases are circular, it is a right circular cylinder.
- If the shape tapers to a point and has a circular base, it is a right circular cone.
Please provide more information about the cylinder's orientation and shape so I can assist you better!
