The Answer of A lamina occupies the part of the disk $x ^ { 2 } + y ^ { 2 } \leq 81$ in the first quadrant. Find its center of mass if the density at any point is proportional to its distance from the x-axis.

A Lamina Occupies the Part of the Disk x2+y2≤81x ^ { 2 } + y ^ { 2 } \leq 81x2+y2≤81

A Lamina Occupies the Part of the Disk $x ^ { 2 } + y ^ { 2 } \leq 81$
