1. r = 2/3 a^2
2. (Original post by AlevelMaths42)
r = 2/3 a^2
What have you tried so far?
3. (Original post by AlevelMaths42)
r = 2/3 a^2
is this R = 2/(3a2 ) ?

or R = (2/3)a2 ?

Well I got a = square root 1.5r. Is that right?

Yep. Though technically it would be plus/minus that answer, but that's another story for a different time.

The second one r=(2/3)a^2
7. Hi,You seem important on TSR. How long do GCSE raw marks stay on the schools system and can I ring up the exam board and ask for my raw mark?

Also, is GCSE maths easier than a level?
8. (Original post by RDKGames)
Yep.
Thanks man
9. A = + sqrt of 3r/2
A = - sqrt of 3r/2

If you're dealing with fractions, keep it in fractions.

Just call up your school and ask for the raw mark, they can be able to help you, rather than the exam board.
