Whats inside length? I think that you must take from circumference not from center O

inside length has to touch 2 points of the circle!

Ah, yes, my bad, diameter is 15, radius is 7.5

I used pythagoras when ABO is a triangle... x^2 +10^2=(5+x)^2

I got 98% and 97% :smile:

:smile:

but last year was really easy :P

Whoa, that's high, and yes, it was, I'm currently solving it :P

4H had better be easier.

I doubt it, 4 h is generally the more difficult of the two.

i would predict that it would be about as difficult/easy as 3H

i counted up all my marks from the answers [osted previously and I got 39 marks. what grade will this achieve????

See the grade boundaries for that were like 82% so I doubt it will be higher than 80 for this cycle :smile:

I always find that I do better in the paper that people do worse in. Weird.

Thank You.

I think you should have a positive attitude towards paper 4H; :biggrin:

:biggrin:

It's going to be easy and those topics will definitively come up so it's not going to be a problem. Is it? :smile:

:smile:

hahah! I'm trying to practise the things that didn't come up.
but they're all the topics I can't do! :P
