Answer:
[tex]A=72\pi\ units^2[/tex]
Step-by-step explanation:
Given that,
The radius of the cylinder, r = 3
Height of the cylinder, h = 12
We need to find the surface area of the cylinder. The formula for the surface area of a cylindrical object is given by :
[tex]A=2\pi rh\\\\=2\times \pi\times 3\times 12\\\\=72\pi\ units^2[/tex]
So, the surface area of the cylinder is equal to [tex]72\pi\ units^2[/tex].
