A cylinder has three faces or individual surfaces. It is a tube-shaped object that is solid on both ends, rather than hollow. It has one face on each end of the cylinder and a third face that wraps continuously around its shaft.
Continue ReadingEach individual surface of a three-dimensional object is considered a face. Faces are separated by edges. A cube has six faces, and a pyramid has four. While the individual surfaces on cubes and pyramids are easy to count because they are flat, faces are not always flat surfaces. They can also be curved, like the third face on a cylinder. Similarly, a cone has two faces and one edge, and a ball has only one face and no edges.

Full Answer >A cylinder is a three-dimensional figure that has two congruent parallel bases, which can either be circles or ellipses, joined by a curved surface. Its shape resembles that of a can of soda or a tissue roll. A cylindrical form can be made by rolling a piece of rectangular paper.
Full Answer >The volume of a hollow cylinder can be found by taking the area of the base and multiplying that by the height of the cylinder. The formula for the area of the base is pi times the radius of the base squared. A numerical approximation for pi is 3.14.
Full Answer >Determining the volume of a cylinder and a prism require similar approaches. Both these shapes have parallel ends. However, by definition, the prism cannot have curves, so a cylinder is not a prism. Volumes are often large numbers, so a calculator is useful in calculating the volume of the prism or cylinder.
