Answer:
250[tex]\pi[/tex] which is around 785 cm (C)
Step-by-step explanation:
Surface area of a cylinder can be found by finding the area of the two circles.
So the diameter of the circle is 10, meaning the radius is 5. (10/2)
[tex]2 * 5^2\pi[/tex] = 50[tex]\pi[/tex]
Multiply by 2 because there are two of these circles.
Now to find the "long part", we find the circumfrence of the circle ([tex]\pi[/tex]d or 2[tex]\pi[/tex]r) and multiply it by the height (15)
10[tex]\pi[/tex] * 15 = 150[tex]\pi[/tex]
add these two up and you get...
250[tex]\pi[/tex] which is around 785 cm. (C)
