The surface area of a cylinder is given by:
 A = 2 * pi * r * (r + h)
 Where,
 r: radio
 h: height
 Substituting values:
 A = 2 * pi * 3 * (3 + 6)
 Rewriting:
 A = 2 * pi * 3 * (9)
 A = 54pi square units
 Answer:
 A = 54pi square units

Surface Area of a Cylinder is given by: 
A = 2πrh + 2π(r^2)

Substituting;
A= 2(π)(3)(6) + 2π(3^2)
A=169.646
