Trigonometry Question
Whats the measurement from the part of the shower that goes in the corner, to the part that shower that the radius arrow points at?

If the arc is exactly a quarter of a circle (i.e. if you put four of them together youd get a perfect circle) then the measurement your after will be very close to 817mm ie the external measurement from the side.
or if its not a quarter of a circle id have a guess at 550 like it says.

If the "radius" is 550mm, then the measurement you are after is 550mm, as ajm stated. The "radius" being the measurment from the centre of the quadrant to the outside, i.e half of the diameter. That drawing is a bit crap.

I know that
but given the question in the first place i was presuming the 550 may be wrong or they may have wanted to know what it would be given it was a quarter of a circle.

I understand the 817mm, but to draw an arc between must be longer than 550mm? In fact it has to be longer than 817??

lol I hadn't even noticed the side measurements!
If you look at this pic:-
I don't think that edge is a pure arc.... it looks like there are two straight parts each side of the curve that blend into an arc of 550mm radius, i.e. the centre of the arc is not in the corner, it must be much further forward.
So we can't answer your question without knowing the length of the straight parts of the arc side!
Edit: unless the straight bit is the 267mm?

Note the 267mm bit on the left hand side. IMHO, I'd suggest that is a straight bit, i.e. not part of the arc. This means there is a 550mm radius arc, plus 267mm of straight section. 550+267 = 817.
Put it another way, the centre point from which the radius is drawn is 267 external (250 internal) in from each edge. This corresponds to square root of (267^2 + 267^2) = 377.6mm diagonally in from the corner. 378+550 = 928mm to the outside of the centre of the arc.

I concur!
