volume of can

Question

The volume of a can is directly proportional to the height of the can. If the volume of the can is 500 square cm when its height is 12.68 cm, find the volume to the nearest whole number of a can with height 14.94cm.

Answer 1

Since they are directly proportional, set it up as a proportion.

 

12.68/500 = 14.94/x

 

Now solve for x by cross-multiplying.

 

12.68x = 7470

x = 589.12

 

So it's 589 cubic cm.
