"These units are not compatible"

[JLand0299]

Can anyone figure out why these two values are not compatible?

Yes - A2 obviously should have dimension "area" but its just a length.

A1*x1 is a volume but A2*x2 is just an area - you can't add a volume and an area.

Possibly you meant r^2 in the formula for A2 (area of a circle with diameter r ?)

You can omit all those unnecessary parentheses and you should use the built-in constant pi instead of your 3.141 (badly rounded anyway).

I had this completed awhile ago, but you are correct I did forget the r^2. Still trying to get the hang of this program. I did also realize the constant pi in the toolbar.

I do appreciate the advice
