Hello!

The total area of â€‹â€‹a cylinder is composed as follows:

Base area + Lateral area

The base area is a circle, so its formula is $$\pi \cdot r ^ 2$$ (however there are 2 circles, up and down, so we multiply it by 2).

The lateral area is $$2 \cdot \pi \cdot r \cdot h$$.

Now, all you have to do is to replace the radius and height with the appropriate numbers and you will have the total area!
