Students find the surface area of 12 cylinders (not drawn to scale). The radius is given for 6 of them, and the diameter is given for the other 6.
There is space to write the area of each part of the cylinder: top base, bottom base, lateral face. This helps students make sense of what surface area is, and will help them understand how to find the surface other of other solids.
You can use this as a practice worksheet, or use it with the color by number picture included for a little more fun!
