Problem
What is the surface area of the cylinder with height \( 4 \mathrm{~m} \) and radius \( 8 \mathrm{~m} \) ? Round your answer to the nearest thousandth.
Solution
Step 1 ：Surface area of a cylinder = \( 2\pi r^2 + 2\pi rh \)
Step 2 ：Plug in the height h = 4 and radius r = 8
Step 3 ：Calculate the surface area: \( 2\pi(8)^2 + 2\pi(8)(4) \)
