In the following exercises, consider a lamina occupying the region R and having the density function p given in the preceding group of exercises. Use a computer algebra system (CAS) to answer the following questions. a. Find the moments M and M. about the x-axis and v-ax is, respectively. b. Calculate and plot the center of mass of the lamina. C. [T] Use a CAS to locate the center of mass on the graph of R. 315. [T] R is the disk of radius 2 centered at (1, 2): p ( x.y)=x 2 +y 2 — 2x—4y+5.
