The dairy owner A uses the                    formula πr2h to find the volume of milk in the mug and charges Rs 43.12 for it. The dairy owner B is of the view that the price of actual quantity of milk should be                        charged. What according to him should be the price of one mug of milk? Which value is exhibited by the dairy owner B? (use π = 22/7)
