Since the radius length is half the length of the diameter, the radius measures 17 ft.

Then, to calculate the surface area, we can use the formula below:

$S=4\pi r^2$

So, using r = 17. we have:

$\begin{gathered} S=4\cdot3.1416\cdot17^2 \\ S=3631.69 \end{gathered}$

Therefore the surface area is 3631.69 ft².
