How to Make a Cone
Draw a semicircle on the paper., Cut out the semicircle., Roll the paper into a cone shape., Glue or tape it together.
Step-by-Step Guide
-
Step 1: Draw a semicircle on the paper.
Lay flat a sheet of paper, or poster board for sturdier projects.
Put the sharp point of a drawing compass on the edge of the paper, then use the pencil to draw a semicircle.
The cone width will be twice as long as the distance between the two compass points.
If you don't have a compass, use another method, like tracing a cup.
Set the compass distance to 9 or 10 inches (23–25 centimeters) for a medium sized hat.To end up with a cone opening with width w, make a semicircle with diameter w x
3.14 (or w x π). -
Step 2: Cut out the semicircle.
Use a pair of scissors or a utility knife to cut out the half-circle shape from the paper. , Lift the two corners of the semicircle and bring them together.
Pull them past each other slightly so the paper overlaps, making an enclosed cone shape. , Run a glue stick or line of white glue along the edge where the paper overlaps, then press it together.
You might need to hold it for a minute or two while the glue takes hold.
You can use tape instead, covering the overlap on the inside and outside of the cone. -
Step 3: Roll the paper into a cone shape.

Step 4: Glue or tape it together.
