Find the surface area of the cylinder in terms of pie. 14 cm diameter and 18 cm for the height. π = the number pi (3.1416...)

Question

r = radius is not the correct way to do this problem any help would be great.
answer are
350cm^2 i think this is correct however how do I do the math to get this.
896^2cm2
602cm^2
644 cm^2

Answer 1

Please learn the difference between geometry and geography. Also, learn the difference between pie and pi.

A . = 2 π r h + 2 π r 2 .

Answer 2

Sorry for the typo's guess I need a keyboarding class. Not grasping it at all.
So I need two radius one for the top one for the bottom then 2 heights?

Answer 3

A cylinder usually has the radius at the top and at the bottom. It also has only one height.
