Math Problem Statement
A hole in the ground in the shape of an inverted cone is 14 meters deep and has radius at the top of 19 meters. The cone is filled to the top with sawdust. The density of the sawdust depends upon the depth, x, following the formula p(x)=2.3+1.5e^-0.5X kg/m^3. Find the total mass of sawdust in the conical hole.

Formulas
Density function: ρ(x) = 2.3 + 1.5e^(-0.5x) kg/m^3
Radius as a function of depth: r(x) = (R/h) * (h - x)
Mass element: dm = ρ(x) * π * r(x)^2 dx
Total mass: M = ∫_0^h dm
