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.
The cylinder is a very common geometrical shape that is seen in everyday items such as garbage cans, canisters, rolled-up carpet, candles, spools of thread and paper cups. It generally has two circular ends, called bases, connected by a rectangular plane. The perpendicular distance between the bases, or the width of the encircling rectangle, is the cylinder’s height.

Full Answer >In an octagon, there are six triangles formed when diagonals are drawn from each vertex. An octagon is a figure that consists of eight straight sides, and it can be either regular or irregular polygons. While irregular octagons do not have sides of equal length, regular octagons do.
Full Answer >There are different ways to find the diameter of a circle depending on what information you start with. If you know the circumference of the circle, divide the circumference by pi to find the diameter.
Full Answer >The measurement of 30 degrees is equal to ?/6 radians. In the unit circle, there are four crucial coordinates. Zero degrees equals zero radians; 90 degrees is ?/2 radians; 180 degrees is ? radians; and 270 degrees is 3/2? radians.
