Cylinder surface area?

Lorena542ByLorena542

Hello, could someone please solve 4a) for me, using the calculation method and the result… I'd like to see if I have it the same way. You have to do some calculations using the base area and the lateral area, but I think you need the perimeter first.

Since you know the radius of the base, you can calculate the circumference yourself.
The base is a circle. The size of a circle is calculated as follows:
U = 2 • π • r
