Influx vs. radius equation, mistake in the dimensions?

I do not know if that definition of Flux is covered in the video you posted, but Flux is defined as energy that passes a unit area per unit time. So Flux has units W/m² or J/(s*m²)

Okay, so I guess that the professor missed out on unit per time. He included only the unit per area.
