A house painter uses a 9.0 inch wide "roller” which is 5.0 inches in diameter to paint a wall with a surface 2.40 m x 6.70 m. The surface includes 2 windows (2.0 ft x 3.0 ft each) which,
obviously, should not be painted. What is the minimum number of times that the painter
has to roll his "paint roller" (one full circle for each roll) in order to apply one layer of paint
on the surface to be painted?
