Answer:

Below in bold.

Step-by-step explanation:

Surface area = 2πr^2 + 2πrh     where r = radius and h = the height

So, we have the equation:

2πr^2 + 2πr*17 = 308

--->   2πr^2 + 34πr = 308

---->   2πr^2 + 34πr - 308 = 0

--->    πr^2 + 17πr - 154

--->  r = [-17π +/- √((17π)^2 - 4*π* -154)]/2π

         = 2.51225, -19.51

We ignore the negative

so the radius r = 2.51 to the nearest hundredth.
