If a cylinder has a radius of 6 ft and a height of 12.2 ft, what is the surface area? Use 3.14 for p.

Okay, So Surface Area Formula:

SA = (R²*3.14*2) + (D * 3.14 * H)

So, Lets Solve.

SA = 6² * 3.14 * 2 + 12 * 3.14 * 12.2

So:

SA = 36 * 3.14 * 2 + 37.68 * 12.2

Next:

SA = 72 * 3.14 + 459.696

Next:

SA = 226.08 + 459.696

Final:

SA = 685.776ft³
