ANSWER
a. 226m³
EXPLANATION
The volume of a cylinder is calculated using the formula:
[tex]Volume=\pi \: {r}^{2} h[/tex]
where r is the radius and h=8m is the height of the cylinder.
The radius is half of the diameter.
This means that:
[tex]r = \frac{d}{2} = \frac{6}{2} = 3m[/tex]
We plug in the values into the formula to get:
[tex]Volume=\pi \times {3}^{2} \times 8[/tex]
[tex]Volume=72\pi[/tex]
[tex]Volume=226.19 {m}^{3} [/tex]
To the nearest cubic meters, the volume is 226 m³.
