Construct and describe simple loci.

I can apply the strategy to problem solving questions involving circles

400m track you take the two semi circles at the ends which is 36.5 then you double it to make the diameter. Then you times it by π which is 229.34m then you divide it by 2 which is 114.67m and that is what the ends are. For the sides you minus 400 with 229.34 which equals 170.66 then you half it which equals 85.33 and that is the length of the sides.
