Use distance formula:-
distance = sqrt [ (x2 - x1)^2 + (y2 - y1)^2) ]
let (x1,y1) = (-3,1) and (x2,y2) = (-1,6) Plug these values in to formula.
A=pir^2
C=2pir
=>r=C/2pi
g(c)=pi(C/pi)^2
A little less than 100. 593 is 7 numbers away from 600, so if you divide 6 by 600 hundred the answer is 100. Since 593 is less than 600, the answer will be less than 100.
