## How do you make a cone shape out of paper?

**Method 2 of 3:** **Making** a **Paper Cone** Using the Folding Method

- Cut out a wide triangle.
^{X}^{Research}^{source} - Roll the far corners of your
**paper**into the centre.^{X}^{Research}^{source} **Make**adjustments to your**cone**.^{X}^{Research}^{source}- Fold the loose edges into the
**cone’s**opening. - Tape the
**cone**.

## How do you make a rectangular cone out of paper?

**Method 2 of 4:** **Making** a Piping **Cone**

- Cut parchment
**paper**into a7 in × 15 in (18 cm × 38 cm)**rectangle**. - Cut the
**rectangle**diagonally to**create**2 triangles. - Curl the short edge towards the bottom edge.
- Continue to wrap the
**paper**into a**cone**. - Fold the end of the
**paper**into the**cone**.

## How do you make a cone layout?

**Learn how to layout a cone in sheet metal**

- First you must find the difference between the large and the small Dia.
- Multiply the large dia. by the vertical height,
- Divide this product by the difference first obtained large dia and small dia)

## How many vertices does a cone have?

Using Faces, Edges, and Vertices to Identify a Solid

Figure Name | Number of Faces | Number of Vertices |
---|---|---|

cone |
1 | |

cylinder | 2 | |

pyramid | at least 4 | at least 4 |

prism | at least 5 | at least 6 |

## How do you work out the size of a cone?

**Circular Cone Formulas in terms of radius r and height h:**

- Volume of a
**cone**: V = (1/3)πr^{2}h. - Slant height of a
**cone**: s = √(r^{2}+ h^{2}) - Lateral surface area of a
**cone**: L = πrs = πr√(r^{2}+ h^{2}) - Base surface area of a
**cone**(a circle): B = πr. - Total surface area of a
**cone**: A = L + B = πrs + πr^{2}= πr(s + r) = πr(r + √(r^{2}+ h^{2}))
