During an experiment, the same type of bacteria is grown in two circular petri dishes. Petri dish A has a diameter of 62 mm and has approximately 45,000 bacteria after 1 hour. Petri dish B has a diameter of 75 mm and has approximately 70,000 bacteria after 1 hour. Determine and state which petri dish has the greater population density of bacteria at the end of the first hour.
