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.Learn More
A scalene triangle has no equal sides. There is no word for a triangle with three different angle sizes. The words describing angle sizes — right, obtuse and acute — reference the degrees of the angle, not their relationships to one another.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.Full Answer >
