Answer 2

Step 1. Find volume of the larger cylinder.
Step 2. Divide this volume by the volume of the smaller cylinders.
What is the formula for volume of cylinder?

Answer 3

phi R^2 times Height is the formula

Answer 4

\[V=\pi r ^{2}h\]
So the volume of the large cylcinder is \[\pi 4^{2}(10)\]The volume of the smaller cylinder is\[\pi 1^{2}2=2\pi \]also in cubic inches.

Answer 5

Ok i that makes sense so far
