Answer:

[tex]A=9\pi\ square\ units[/tex]

Step-by-step explanation:

we know that

The base of the cylinder is a circle

The area of the circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=6/2=3\ units[/tex] ----> the radius is half the diameter

substitute

[tex]A=\pi (3)^{2}[/tex]

[tex]A=9\pi\ units^{2}[/tex]
