A scientist is studying an object in space. He approximates the density \( D(x) \) (in \( \frac{g}{\mathrm{~cm}^{3}} \) ) of the object \( x \) years after its origin by the following equation. \[ D(x)=\frac{x+4}{9 x^{2}-24 x+17} \]

An astronomer has discovered a new planetoid about 1.2 $\mathrm{AU}$ from the Sun. According to the line of best fit, which of the following best approximates the density of the planetoid, in grams per cubic centimeter? \begin{equation} \begin{array}{l}{\text { A) } 3.6} \\ {\text { B) } 4.1} \\ {\text { C) } 4.6} \\ {\text { D) } 5.5}\end{array} \end{equation}
An object occupies the region between the unit sphere at the origin and a sphere of radius 2 with center at the origin, and has density equal to the distance from the origin. Find the mass.
