Problem
Find the surface area of a cylinder with a height of \( 7 \mathrm{yd} \) and a base radius of \( 2 \mathrm{yd} \). Use the value 3.14 for \( \pi \), and do not do any rounding. Be sure to include the correct unit.
Solution
Step 1 ：\mathrm{Surface\ Area} = 2\pi r^2 + 2\pi rh
Step 2 ：\mathrm{Surface\ Area} = 2\pi (2^2) + 2\pi (2)(7)
Step 3 ：\mathrm{Surface\ Area} = 88.96 \mathrm{yd}^2
