A cylinder contains 2 faces that are circles and a rectangular prism contains 6 faces that a a rectangle.
a cylinder has two faces that are circles
The faces of a cylinder are circles.
There is no shape which has only circular faces.
A rectangle and two circles.
no faces
The two solid figures that have at least one face that is a circle are the cylinder and the sphere. A cylinder has two circular faces at its ends and a curved surface, while a sphere has a continuous curved surface with no flat faces. Both shapes are commonly found in various applications in geometry and real-world objects.

rectangles and circles
Faces of cylinder are circular therefore area must be pi*radius*radius That is the formula for the top and bottom faces, the circles. However, the main face, the face connecting the two circles, is really a large rectangle bended to fit with the circles. The height of the rectangle is the same as the height of the cylinder. The width of the rectangle is the circumference of the circle (pi * 2 * radius). The formula for a rectangle is width * height. So, the side face is height of cylinder * circumference of circle (pi * 2 * radius.)
