Given that ally, Sue, John and Joe were arguing about the formula for the surface area of a cylinder.

Let's select the correct formula(s) for the surface area of a cylinder.

Apply the formula for the surface area of a cylinder:


SA=2\pi rh+2\pi r^2

Now, let's factorize the formula:

Factor out 2πr:


SA=2\pi r(h+r)

Therefore, the correct formula from the list is:


2\pi r(h+r)

• ANSWER:

d. 2πr(h + r)
