I meant frictional unemployment rate

I'm sorry, I'm not following what you did. I get that we know dx/dt = 12mm^2/hr and we want to find dr/dt but I don't know how you linked them together as a function of r. Maybe show me more steps and how you got the derivative dr/dt. Thanks

You got the answer pretty much right but a more exact answer would be 8/3 or 2 2/3. Because in decimal form it is actually 2.66666667

12mm^2/hr = r2PI dr/dt So 12/2PIr mm^2/hr = dr/dt which is the same as dr/dt = 6/PIr mm^2/hr Why'd you originally say dr/dt= 12/(2r) mm/hr

ok thanks jimmy and Ms.Sue
