Answer:
The ratio of the total surface area to the lateral (curved) surface area of the cylinder is 5:3
Explanation:
The height of a right circular cylinder is 1.5 times the radius of the base.
Let the radius of base be x
So, Height of a right circular cylinder = 1.5x
Total surface area of cylinder =

Curved surface area of cylinder =

So, Ratio of the total surface area to the lateral (curved) surface area of the cylinder =

Hence the ratio of the total surface area to the lateral (curved) surface area of the cylinder is 5:3
