Question

The volume of a cylinder is 225pi cmand its radius is 5 cm.What is the length of the cylinder's height?o 9 cmo 5 cmo 10 cmo 7 cm

Answer 1

The formula for the volume of the cylinder is given by:

`V=\pi\cdot r^2\cdot h`

Where:

r = radius

h = length of height

Substitute the given values:

`225\pi=\pi\cdot(5)^2\cdot h`

And solve for h:

`\begin{gathered} 225\pi=\pi\cdot25\cdot h \\ (225\pi)/(25\pi)=(25\pi h)/(25\pi) \\ h=9 \end{gathered}`

Answer: 9 cm
