Question

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a radius of 9 feet and a height of 18 feet. Container B has a radius of 7 feet and a height of 19 feet. Container A is full of water and the water is pumped into Container B until Container B is completely full.

To the nearest tenth, what is the percent of Container A that is full after the pumping is complete?

Container A
r = 9
h = 18


Container B
r = 9
h = 19

Answer 1

63.85% of Container A is full after the pumping is complete.

Explanation:

Cylinder A = π · 9² · 18 = 4580.44 square feet

Cylinder B = π · 7² · 19 = 2924.82 square feet

4580.44 ÷ 2924.82 = 1.5661

100 ÷ 1.5661 = 63.85
