make everything into twelfths, so you have... 9/12k-2/12 =6/12 take out the 2/12 so... 9/12k=8/12 so now you divide 8/12 by 9/12 = 8/12*12/9 = 96/108 and simplify to 8/9 so k = 8/9

so basically you have a circle, right? and the equation of a circle is x^2+y^2 = r^2 so in this case your r, or radius is root of 64, or 8 if the radius of the circle is 8, use the formula for circumference of a circle (c=2pi(r)) to find the length of fencing so... c=2pi(8) so...
