<h3>Question asks, "Find the surface area of a <em>cylinder</em>."</h3>
Answer is: D. 352 pi ✅
<h3>Why is that the case? Let's see.</h3>
When finding surface area, multiply two times pi times the radius times the height.
Now, you need to split these four values into an actual equation.
<em>2 followed by pi radius-height plus two pi radius, is actually the formula for surface added to the formula of area, so;</em>
Solve.
<em>the result is 1105</em> <em>according to order of operations.</em>
<em />
Divide 1105 by pi to get the answer. Pi is 3.14... so for every 3.14..., you count that as one.
<em>which rounds to 352</em>
<em />
Therefore, your answer is 352π units²
