    The total area of ​​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!
