b. Convert the integral _(E)g(x,y,z)dV to cylindrical coordinates and evaluate it. g(x,y,z)=(1)/(x+3),E={(x,y,z)|0 =0,0

b. Convert the integral _(E)g(x,y,z)dV to cylindrical coordinates and evaluate it. g(x,y,z)=(1)/(x+3),E={(x,y,z)|0<=x^(2)+y^(2)<=9,x>=0,y>=0,0<=z<=x+3} g(x,y,z)=x^(2)+y^(2),E={(x,y,z)|0<=x^(2)+y^(2)<=4,y>=0,0<=z<=3-x} g(x,y,z)=x,E={(x,y,z)|1<=y^(2)+z^(2)<=9,0<=x<=9-y^(2)-z^(2)}I need help with 245 and 255 please
