Thanks so much!

Okay, thanks!

So, should I say (-2,-2)?

Good job, Omi and asinus!

My solution.

To find the surface area of a cylinder expand the middle portion to a rectangle.. Then, take the 2 tops and find the area of each of them... After that, add the area of the 2 circles with the area of the rectangle!

Um,,, what is x?

Yes, it is. Very short way!

fROM COOLMATH : All sides All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the interior angles, we know that the sum of all the angles is 540 degrees (from above)... And there are five angles... So, the measure of the interior angle of a regular pentagon is 108 degrees.are the same length (congruent) and all interior angles are the same size (congruent).
