so a hint might be
could you describe the furthest point from the origin
maybe in words
or maybe sketch it
do i find the distance from the origin to the centre and then add that difference onto the centre coordinates?
I have but im unsure of where to go from here
ah no not quite
so what you might notice tho is that
the furthest point is on the same line from the origin to the centre
right?
ah yes
like if you go origin to centre, and then carry on
yhyh
thats as far away as you can go
ok awesome so
so did you find the distance from origin to centre
yes i got 5
ok awesome
and then if i asked you the distance from the centre to the edge of the circle
what would you say
the radius
nw!
love
