A water ride at a local water park has a ride shaped like a cone that acts like a funnel whereby guests swirl around the cone until they drop through its center. There is one ride for adults and a similar, smaller version for children. If the adult ride has a radius of 33 feet and the child ride has a radius of 22 feet, what is the ratio between the volumes of each ride?

Question

ganpat · Answer

Volume of Cone = 1/3 * pi * r square * h


Volume adult/ Volume childrens

 = (1/3 * pi * r square * h) adult / (1/3 * pi * r square * h) children 

 = ( 33 * 33)/ (22 * 22) = 9/4..

assuming for same height.. and rest all terms get cancelled.. 

understood ??
