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:
[tex]SA=2\pi rh+2\pi r^2[/tex]
Now, let's factorize the formula:
Factor out 2πr:
[tex]SA=2\pi r(h+r)[/tex]
Therefore, the correct formula from the list is:
[tex]2\pi r(h+r)[/tex]
• ANSWER:
d. 2πr(h + r)
