Imagine the cylinder is a stack of thin plates with radius 3. The surface area of the cylinder will be the total of the circumferences (the distance around the outside) of all the plates.
First, you need to figure out the circumference of a plate. Circumference equals pi (3.1415926...) times the diameter. (You can probably round pi to four digits for this problem.) The formulas in this specific case are:
Circumference = pi multiplied by the diameter (3+3)
Surface area = Circumference multiplied by the height of the cylinder (8)
The problem doesn't indicate if the cylinder is hollow, so you may need to add the areas of the top and bottom to get the total surface area. The formula for the area of a circle is pitimes the radius squared (3x3).
