Short Answer

Expert verified

The expression 鈭�惟xdA鈭�惟dArepresents the center of mass located within the region 惟with constant density function 蚁(x,y)=1.It is measured from y- axis and measured in centimeters. Its symbol is x炉.

x炉=鈭�惟xdA鈭�惟dA

The expression 鈭�惟ydA鈭�惟dArepresents the center of mass located within the region 惟with constant density function 蚁(x,y)=1. It is measured from x - axis and measured in centimeters.

y炉=鈭�惟ydA鈭�惟dA
