I hate questions that use unknowns and ask you to say which ones represent areas.
I need help on this question, please help. The question is as follows
Here are some expressions
πa^2 + πb^2
The letters a,b and c represent lengths. π(pi) and 2 are numbers that have no dimentions.
Two of the expressions could represent areas, which two?
AH! Do you see why im stuck!?!
