A tube has a radius of 4 inches and a height of 4 inches. What's its approximate volume?

201.06

Explanation

For cylinders, \(\text { Volume }=\pi \mathrm{r}^{2}(\mathrm{~h})\) .In this problem, \(\mathrm{V}=\pi\left(4^{2}\right)\)If you assume π is approximately 3.14 then V is approximately equal to (3.14)(16)(4) or 201.06 cubic inches.
