Hint: In your triple integral in polar coordinates the limits on the z integral are 0 and 6-y-x, put the limits in polar form.
Could you please help me with this problems??? 1)Find the volume of solid bounded by planes x+y+z=6, z=0 and the cylinder= x^2+y^2=4
2)Find the volume of solid bounded by planes z=3x,z=0and the cylinder= x^2+y^2=1
I can't find the results when I put the polar coordinates
i posted an image to show you how i started..i used double integrals alike this problem Multiple Integrals 9: Finding Volume Problems (Cylinder) - YouTube ..but probably this way is wrong..it would help me if you could tell me you opinion!!!
