2. Find the concept and extract it into the section.
3. Write the formula:
For example:
column
S-pillar = perimeter of bottom multiplied by height
S bottom area =πr? ×2
S transverse area = perimeter of bottom multiplied by height.
V= bottom area times height.
circular cone
S bottom area =πr? ×2
V= the area of a base multiplied by the height × one third (and one third of the volume of a cylinder with equal base and height).
4. Add pictures (preferably about cylindrical cones)
5. Brighten the edges of the board with colored pens.
6. Finish (write your name, don't forget! )
