Question

Find the surface area of this figure. Leave the answers in pi if applicable.

Answer 1

We will have that the surface area of the cylinder will be:

`\begin{gathered} A=2\pi(2cm)(7cm)+2\pi(2cm)^2\Rightarrow A=28\pi cm^2+8\pi cm^2 \\ \\ \Rightarrow A=36\pi cm^2 \end{gathered}`

So, the total surface area of the cylinder is 36pi cm^2.
