Which equation is used for the development of a cone where R radius of Cone Circle R slant height of the cone?

The length of any of the straight lines joining the vertex to the circle is called the slant height of the cone. Clearly l2 = r2 + h2 , where r is the radius of the base.

How do you find the angle of a cone?

the angle of the sector differs from the angle of the cone.

  1. the sector’s angle is computed using the formula θ=LR; where L is the sector’s arc length and R is the sector’s radius.
  2. now you can find r to be Rθ2π.
  3. the cone’s lateral side is R (the sector’s radius).
  4. let’s call the top vertex of our triangle α2.

What is the formula for the circumference of a cone?

The diameter d = 2 times the radius r, d = 2*r. In the diagrams, h is the height of the cylinder and the cone, and r is the radius of their bases, which are equal. The circumference C of a circle is C = 𝜋d or C = 2𝜋r. And using the Pythagorean Theorem, we can find the slant height s of the cone, s = √(h² + r²).

What is the perimeter of cone?

Formula for geometrical figures

Perimeter formula
Square 4 × side
Cylinder pi × radius2 × height
Cone (1/3) × pi × radius2 × height
Pyramid (1/3) × (base area) × height

How do you draw a cone diagram?

You can also find the step by step tutorial to create this Cone Diagram in any Powerpoint version below:

  1. Step 1: Create a circle. Go to ‘Auto shapes’ menu and pick the ‘Oval’ tool.
  2. Step 2: Give it a 3D perspective.
  3. Step 3: Add bevel to the ‘Top’ surface.
  4. Step 4: Add width and height to the bevel.

How do I make a cone in Word?

For example, to create a cone out of a circle, follow these steps:

  1. Right-click a toolbar and select Drawing.
  2. Click the Oval button in the Drawing toolbar.
  3. Click and drag to draw a circle in your document.
  4. With the circle selected, click the 3-D style button in the drawing toolbar.

How do you make a cone shape?

The easiest way to make a cone is to start with a semicircle, then overlap the straight edges until they form a cone shape. If you want to get more specific, however, you should start with a circle instead, then cut a wedge out.

How do you make a wooden cone?

In short:

  1. Cut a bunch of wedges from rectangular blocks. If you glued them together at this stage, it would make a near-cylindrical drum.
  2. make a diagonal cut into each wedge to make the triangular size of the cone you need.
  3. Glue them together into a conical blank.
  4. Sand the corners down or use a router jig.

How do you make a small cone hat?


  1. 1Draw a half-circle. Draw a half circle on construction paper using a compass or a pencil tied to a string.
  2. 2Cut out. Cut out the half circle.
  3. 3Form a cone.
  4. 4Staple at the base.
  5. 5Glue the seams.
  6. 6Press at the seams.
  7. 7Remove the staple.
  8. 8Decorate the cone hat.

How do you make a Schultuete?

Decorate with stickers, glitter or jewels, or cover it with a movie poster or pictures. Set the cone aside and lay out two pieces of gift tissue, one on top of the other, with the longer side toward you on your work surface. Smooth the folds with your hands. This gift tissue will become the top of the schultuete.

How do you cut fabric to fit a cone?

  1. Draw a large circle on paper with a compass and pencil.
  2. Cut the circle out with scissors.
  3. Fold the circle in half, then fold in half again.
  4. Pin the paper circle to fabric (skip this step if you are making a paper cone), then cut out the fabric circle.
