Answer:

  720 cm²

Step-by-step explanation:

You want the surface area of a radius 6 cm cylinder 14 cm high, using π=3.

Area

The area formula can be factored as ...

  A = 2πr² +2πrh

  A = 2πr(r +h)

  A = 2(3)(6 cm)(6 cm +14 cm) = 720 cm²

The surface area of the cylinder is approximately 720 cm².
