1. The problem statement, all variables and given/known data Find the center of mass of the solid of uniform density bounded by the graphs of the equations: Wedge: x^2+y^2=a^2. z=cy(c>0), y>=0, z>=0 2. Relevant equations Mx=int(y*p(x,y) dA) dA=area of integration, dydx/dxdy 3. The attempt at a solution I set up all the equations for Mx, My and x-bar, y-bar but I cant seem to realize what the limits of integration are. I can't see how the z=cy comes into play at all. Does it imply its a 3 dimensional figure or what?
hi haxtor21! (have an integral: ∫ and try using the X^{2} and X_{2} icons just above the Reply box ) it's a vertical cylinder (x^{2} + y^{2} = a^{2}), sliced by a plane through the x-axis and sloping at 45°
