Tutorial, how to make volumetric 3D CYLINDER from A4 paper. ***************** Today we are making a paper geometric figure called a cylinder. How to understand what a cylinder is. If you are just embarking on complex figures in mathematics, then in understandable words a cylinder is a geometric body that is formed if you start to rotate a rectangle around one of its sides. He is studied in more detail on geometry at school. In such lessons, children learn in detail about the properties of this figure, learn to measure the area, calculate the volume of the cylinder. As a rule, there are flat and three-dimensional geometric figures. Very often, students are asked at home to make a volume cylinder with their own hands. Indeed, in the process of creating such a figure, the student will precisely consider all the sides, understand what the cylinder consists of and it will be much easier for him to apply various formulas to this kind of geometric shapes. There are many schemes for making a cylinder, but we offer an easy way. You do not need compasses, and also do not have to draw with a pencil, you do not need to print templates. The ideal material for such a voluminous figure will be paper, moderately thick. Materials: 2 sheets of A4 paper, glue, pencil and scissors. Take A4 sheet, pencil, scissors and glue. First you need to bend the sheet in half, for the reliability of the paper figure, then roll up the paper with a tube, pre-spread with glue. Glue the top and bottom...
