Calculate Cone Volumes & Cone Surfaces

For a perpendicular cone - one which the height is measured from the centre of the base, the formulars are...

Surface Area = πrS + πr2

where S = √(h2 + r2)

Volume= ⅓πr2h



Radius (r)
Height (h)
Slant Edge (S)
Volume (V)
Lateral Surface Area (ls)
Total Surface Area (ts)
