[resolved] mathematics help ... dome volume?

[illskills]

I have found the formula for determining the volume of a hemisphere.

but say my hemisphere's depth changed how would i figure out the volume ?

would help if i knew the name of the object im looking for, is hemisphere the correct search term ?

any help greatly appreciated.

ignore my post ... i needed dome volume calculation rather than hemisphere found it

can some one please have a look @ this and tell me if its right ?

(calculates the volume of a dome)
Dim dVolume As Double = (Math.PI * (dHeight / 6)) * ((3 * dDiameter) ^ 2 + (dHeight) ^ 2)

Why not just follow the last equation exactly?

volume = Math.PI * radius * height ^ 2 - (Math.PI * height ^ 3) / 3

thanks for your reply i was struggling to get matching results calculating using the hemisphere calc & dome calc using the the same variables .... ill check this out a little later

thanks again
