	all calculators / Cone CALCULATOR: ...enter known values for cone radius & height ... then click GET button. No letters or units (e.g. enter 22 not 22 cm)	Formula / equation:
	ENTER Cone Radius >	= r
	ENTER Cone Height (h) >	= h

	Cone Side =	= s (length of slope / slant / side)
	Cone Circumference =	= 2 π r (circumference of base of cone)
	Cone Base Area =	= π r² (area of circle that forms base of cone)
	Cone Curved Surface Area =	= π r s (surface area of the sloping wall of the cone)
	TOTAL CONE AREA =	= π r² + π r s (area of base + area of wall)
	CONE VOLUME =	= 1/3 (π r²)h (one third base area x height)

	Figure shows a cone with equations (formulae) for circumference, circle area, surface area, and conical volume. This cone also available as a 3D stereo anaglyph.	This calculator will work out the surface area of a cone and the volume of a cone if you enter the cone radius and height. Only enter numbers (e.g. enter 22 not 22 cm). If you try to enter a unit of measure (e.g. 22 metres, 4 miles, 10 cm) you will get an NAN (Not A Number) error appear in each box. When you have entered the numbers, click the GET button. SURFACE AREA OF A CONE is the area of base (π r ²) + area of the sloping wall π r s. VOLUME OF A CONE is the area of the base (π r ²) times the height (h) divided by three = 1/3 π r ² h. To convert between lengths (e.g. centimeters to inches) see our Length & Distance Converter. For weights and volumes (especially in recipes) see our Recipe Converter.
