How can we calculate the volume of limestone pile? (in cement industry)

Volume of Limestone Pile
How can we calculate the volume of Limestone Pile by formula?
Can we calculate this by using the formula,
V = (L x W x H)/2 + (π r2)/3
where
L = Length of Pile
W = Width of Pile
H = Height of Pile
r = Radius of Cone
I have confusion using this formula. The L, W , H and r are not cleared to me.
Can anybody help...
