A cylinder whose radius is 2 inches and whose height is 5 inches is used as model to produce a cylinder with dimensions 25 times larger than the ones from the model. How many times greater is the volume of the larger cylinder than the smaller cylinder?

If the dimensions of the new cylinder are 25 times larger, what is the new cylinder's radius? It's height?
Now that you know those two, what is the new cylinder's volume? (Volume = (area of base) * height (for a cylinder)) How many times larger is that than the original cylinder's volume?

first find the area of the circle on the base or top. then multiply that by 5 in. that's the volume of the model. multiply the volume by 25 and that's the answer to the the bigger cylinder. take the volume of the big cylinder minus the volume of the model. that is the difference in inches.
i'm not sure of the formula to find the area for a circle though. you'll have to look it up.
