True
I’m not 100% positive but I’m pretty sure
Lets rule some out off the bat, shall we?
The first one you mentioned, a circle is a plane figure with no straight sides... I can name another shape with no straight sides... an oval.

The last one mentioned is also a true statement.
4:5 is the same as 4x:5x where 4x is compound A and 5x is compound B.

Then amt of compound B is 5x = 5(477/4) = 596.25 ml
Solve for one side using base times height divided by two the answer will be the same for both sides so add them
