Answer:

250
\pi which is around 785 cm (C)

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)


2 * 5^2\pi = 50
\pi

Multiply by 2 because there are two of these circles.

Now to find the "long part", we find the circumfrence of the circle (
\pid or 2
\pir) and multiply it by the height (15)

10
\pi * 15 = 150
\pi

add these two up and you get...

250
\pi which is around 785 cm. (C)
