### The radius of a cylinder is halved and the height is tripled. What is the area of the curved surface when compared to the same area previously?

1.5 times

Step by Step Explanation:
1. The curved surface area of a cylinder is 2πrh.
2. If the radius is halved and the height is tripled.
3. Putting this into the formula, we see that the curved surface area becomes:
2π ×
 1 2
× r × 3 × h
= 1.5(2πrh)
= 1.5 times.
