Answer: 1:1
Step-by-step explanation:
Let r be the radius and h be the height of a cylinder.
Formula: Curved surface area of cylinder = 
Now, if radius of a cylinder is doubled and its height is halved, then new radius will be R= 2r and new height will be 
Now, new surface area = 
Ratio of curved surface areas : 
Hence, the ratios of their surface areas = 1:1 .
