Hi all, I would appreciate some help with the problem:

The problem state: "A building design consultant is going to make a 14 foot diameter windowwith a vertical cut through the glass so that 2/3 of the glass can be tinted. Wheres should this cut be made?"

As you can see in the above attachment, I was able to conclude into some sort of equation, but when I solve that equation to 49*pi/3 via wolfmath, I got about 6.83 = x, which does not make sense because the radius is 7 and that wouldn't be 1/3 if you draw the vertical line through it to divide the circle.

If you could help me out, I would really appreciate it.

Thank you,
