Hint: A cylinder whose bases are circular in shape and parallel to each other is called the right circular cylinder. It is a three-dimensional shape. The axis of the cylinder joins the centre of the two bases of the cylinder. We visualize an image of a cylinder and count all the surfaces.

Complete step by step solution:

The number of surfaces in the right circular cylinder is 3. Where one side is the upper side, one the lower side and one, the lateral one.

Note: A right circular cylinder is a cylinder that has a closed circular surface having two parallel bases on both the ends and whose elements are perpendicular to its base. It is also called a right cylinder. All the points lying on the closed circular surface is at a fixed distance from a straight line known as the axis of the cylinder. The two circular bases of the right cylinder have the same radius and are parallel to each other. It is one such geometric shape which is used frequently in real life. Basically, to derive the formulas for area and volume of the cylinder, the right cylinder is considered.
