Do we know how thick the icing is going on?

C=2piR C=14pi

The volume in cubic inches of icing to cover the cookie uniformly to thickness t would be\[V(r,t)=\pi r^2t\]For this particular problem, \[v(7,t)=49\pi t\]

Should have been a capital V in the second equation.....

I don't think the circumference has too much to do with this problem.

I would think volume will give the amount of icing it takes to make a cake, but what you use around it. I agree circumference concerns with the top not surrounding...but can you explain a little for the volume?

That's the way these things are measured. Just like if when you paint, you cover a given area, but you measure the amount of paint in liquid measure (volume). If you assume icing always goes on at a particular thickness, you could just determine the area, but I think that's a math book answer without any real-world value.
