Question

Two cylinders are partially filled with water, each to a depth of 24 feet. The smaller cylinder has a radius of 3 feet and the larger has a radius of 4 feet. Water is emptied from the larger cylinder into the smaller cylinder until each holds an equal volume of water. What is the difference between the depths of the two cylinders in feet and inches?

Can you help me please?

Answer 1

You can ignore π

(3^2+4^2)*24)/(2*3^2) - (3^2+4^2)*24)/(2*4^2) = (4^2-3^2)(4^2+3^2)/(2*3^2*4^2) = 14 7/12 = 14'7"
