Answer:

207.24 in²

Step-by-step explanation:

When the diameter is 6 inches, the radius is 3 inches, half the diameter.

We can rearrange the formula to make it a little easier to calculate:

SA = 2πR(R +H)

Substituting the given values, R=3, H=8, π=3.14, this becomes ...

SA = 2(3.14)(3)(3+8) = 207.24 . . . . square inches

The surface area of the cylinder is 207.24 square inches.
