A centrold is an object's geometric center. For an objector uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by$,$ first, cutting the body into regular shaped segments, and then by calculating the weighted average of the segments' centroids. An object is made from a uniform piece of sheet metal. The object has dimensions of $a=1\mathrm{.}45ft,$ where $a$ is the diameter of the semi$-$circle, $b=3\mathrm{.}70ft,$ and $c=2\mathrm{.}45ft.$ A hole with diameter $d=0\mathrm{.}750ft$ is centered at $(1\mathrm{.}13,0\mathrm{.}725).$
