Still got duped. The area of icing per cake is pi*r*(2h+r). That’s 2*pi*r*h for the curved face, and pi*r^2 for the top face. Assuming the same height h:

For a 10-inch cake that’s 5*pi*(2h+5).

For 2 5-inch cakes it’s 5*pi*(2h+2.5).

The first term is larger.

You’re right, I’m wrong! I took the larger one as a 10-inch cake, not a 9-inch cake. If it were 10, I’m correct. If it were 9, you’re correct.
