semi vertical angel =α
height = h units
let radius = r units
tanα =radius/height
radius, r = h tanα
now, volume = (1/3)πr²h
=(1/3)π×(htanα)²×h =(1/3)πh³ tanα² cubic units
height = h units
let radius = r units
tanα =radius/height
radius, r = h tanα
now, volume = (1/3)πr²h
=(1/3)π×(htanα)²×h =(1/3)πh³ tanα² cubic units
