There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D.
D= Diameter
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
You can't find the perimeter of a cone because it's a 3D shape, but you can find the volume; the formula is 1/3x3.14xr2xh (r= radius of the base/ h= height).
the Circumference is pi times 2 times radius If you know circumference then you can find the radius. once you know the radius just multiply by 2 to find the diameter.
circumference=r2pi
The unit for a circumference is the same as the unit for length (or radius or diameter).
pls tell me how to find development for cone which is half cutted
Jason Laosher
Circumference of a circle = (pi) x (diameter)
diameter times 3.14159
Some of many examples are:- Finding the circumference of a circle Finding the area of a circle Finding the surface area of a sphere Finding the volume of a sphere Finding the surface area of a cylinder Finding the volume of a cylinder Finding the volume of a cone Finding the surface area of a cone
Divide the circumference by 2*pi because 2*pi*radius = circumference
Find cone base area using a circle's formula, which is pi times (radius squared). Find cone slanted area with this formula:half of the length of the side, times the circumference of the base.. Add the results to get the total surface area.Measure the cone's circumference with this formula: C = pi * d. C is circumference and d is its diameter. Measure the diameter, which is a line from the base's one side, through its center, to the opposite side.Calculate cone slant height from its top to its base's side. Use your slant height and circumference measurement to calculate cone slanted area. Use step one's formula, where "s" is the slant height, and C is the circumference.4 Add your results for cone base area and cone slanted area to get the total cone surface area.
2r+pi r
PI times the DIAMETER
3.14 to the 2 power
The formula for the circumference of a circle is pi * diameter or (2 radius.)
It is the formula for finding the circumference of a circle which is the same as 2*pi*radius
