Hollow Right Circular Cylinder

The internal and external diameter of a hollow long right circular iron cylindrical pipe of height $4$ metre are $3.5 \mathrm{cm}$ and $4.2 \mathrm{cm}$. If the weight of one cubic decimetre of iron is $5 \mathrm{kg}$, find the weight of the pipe.

The amount of metal in a hollow cylinder with height $14$ decimeter and external diameter $5$ decimeter is $42.24$ cubic decimeter. Find the thickness of the cylinder.

Two right circular beakers of same diameter and heights $8.5 \mathrm{cm}$ and $9.5 \mathrm{cm}$ contain dilute acid. That acid is poured into a large beaker of diameter $10.5 \mathrm{cm}$ and then the height will be $8 \mathrm{cm}$. Find the diameter of the first two beakers.
