Answer: They will be watered together every 28 days.
Surface area of a cylinder = 2 x Pi x r^2 + 2 x Pi x r x h
R = 27 cm
H = 37 cm
Take away the Pi seeing as you want to keep it in terms of Pi
2 x 27^2 + 2 x 27 x 37 = 3456 Pi cm^2
Your answer is B
If they do not have solutions (intersections).
If they do not have intersections then they must be parallel. Imagine it on the graph
