GEOMETRY help me please

For this case we have that by definition, the volume of a cylinder is given by:
[tex]V = \pi * r ^ 2 * h[/tex]
Where:
r: It's the radio
h: It's the height
We have as data that:
[tex]r = 7\\h = 16[/tex]
Substituting the data we have:
[tex]V = \pi * (7) ^ 2 * 16\\V = \pi * 49 * 16\\V = 784 \pi[/tex]
So, the cylinder volume is[tex]784 \pi[/tex]
Answer:
[tex]784 \pi[/tex]
