Answer:
The surface area of a cylinder can be calculated using the formula:
SA = 2πr^2 + 2πrh
where r is the radius of the base of the cylinder, h is the height of the cylinder,
Substituting r = 3 and h = 1 into the formula, we get:
SA = 2π(3)^2 + 2π(3)(1)
SA = 2π(9) + 2π(3)
SA = 18π + 6π
SA = 24π
Therefore, the surface area of the cylinder is 24π square units.
