Question

4. A cylinder has a volume of 198 cm^3,and itsbase has an area of 22 cm^2.What is theheight of the cylinder?Please hurry

Answer 1

1) Let's find out the height of that cylinder, by plugging it into the formula:

$\begin{gathered} V=\pi\cdot r^2\cdot h \\ 198\text{ =}\pi\cdot rh \\ \end{gathered}$

2) The Base area is given by:

$\begin{gathered} A_B=\pi\cdot r^2 \\ 22=\pi\cdot r^2 \\ \frac{22}{\pi}=\frac{\pi}{\pi}r^2 \\ r=\sqrt[]{\frac{22}{\pi}} \end{gathered}$

So now let's plug that radius
