Can someone explain this to me.
Minimum Required Opening Distance for a Coaxial Piston Valve

Abarrel=pi*r^2
Avalve=2pi*2r*X(open)
Abarrel=Avalve
pi*r^2=4piRX(open)
X(open)=R/4

I understand the area calculation for the barrel, that's just a circle. I don't understand the area for the valve though. What kind of shape is that calculating for? Someone please help.
Thanks

No, no no. I'm want to know what shape that is that he is getting the formula from. I know I'm calculating how far the valve is opening.
