Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a radius of 5 feet and a height of 20 feet. Container B has a radius of 6 feet and a height of 17 feet. Container A is full of water and the water is pumped into Container B until Container A is empty. To the nearest tenth, what is the percent of Container B that is full after the pumping is complete?
