None of the given answers are correct.  To find the surface area you will find the areas of each circular base by using the formula for area of a circle.  

To find the area of the circular height, you will find the circumference of the circle and multiply by the height.

SA = 2(pi x r^2) + pi x d x h
        2 x pi x 3^2 + pi x 6 x 12
        18pi + 72pi
SA = 90pi.

The surface area would be 90 pi square inches.

Solving Rational Equations. LCD Method. Show work.<br><br><img src="https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5x%7D%20%2B%5Cfrac%
Svet_ta [14]

using the LCD method.... well, there are a couple of ways, but let's simply add them up.

well, the denominators are 5x and 2x... so the only LCD will just be 10x, since it's divisible by both, so let's use that one.

\bf \cfrac{2}{5x}+\cfrac{7}{2x}=1\implies \stackrel{\textit{LCD of 10x}}{\cfrac{(2)2~~+~~(5)7}{10x}}=1\implies \cfrac{4+35}{10x}=1\implies \cfrac{39}{10x}=1 \\\\\\ 39=10x\implies \cfrac{39}{10}=x\implies 3\frac{9}{10}=x
