Calculate the flux of the vector field (x³, y³), out of the annular region between the x² + y² = 9 2 and x² + y² = 25.

Calculate the flux of the vector field F = 6i + 2x²j – 2k, through the square of side 4 in the plane y = 7, centered on the y-axis, with sides parallel to the x and z axes, and oriented in the positive y-direction. flux =
