Answer: C - 36.8cm^2
Step-by-step explanation:
Surface area of a cylinder formula: A=2πrh+2πr^2
Since a drinking straw is open on both ends, we will not need to find the area of the two circles that would normally be on the top and bottom of a cylinder. Therefore, our equation becomes A=2πrh.
Let's plug in the radius and height into the equation: A = 2(π)(0.3)(19.5)
After multiplying these numbers together, our answer is A = 36.8cm^2 , which is option C.
Hope this helps!! :)
