The formula for the surface area of a right cylinder is 2πrh + 2πr^2. r is the radius, and h is the height.
In this instance, the radius is 4, so plug that in for r. (I.E. Replace r with 4).
The formula is now 2π4h + 2π4^2.
Next, plug in the height, 8 for h.
Now we have 2π4(8) + 2π4^2, which is approximately 301.59.
The surface area is 301.59. (Unit of measure was not specified)
