You can select the bend option use one of the edges you want to bend and then specify a 360 degree bend and use the inside circumfrence as the bend radius. Its probably not the best way to create the part but it should work. Of course this could be dependent on what version of Proe/Creo you are running. It may not be this simple in older versions of Wildfire.
I created revolve wall as my first sketch, then if i follow second of your step I ma not able to complete the sketch (Rip). Find the image & help me ..which option i should go with ?
Does it NEED to be in sheetmetal? Maybe use a spinal bend? Then it's easy to calculate the radius by the developed length (circumference). 
I was waiting for that one, Frank However, using the revolve in sheetmetal will let you easily manage the ID or OD. If you need control of the angle where features are located, you can use a reference dimension in the flat state to specifically locate features at the appropriate clocking angle.
I bet there are a dozen ways to accomplish this and still end up with a sheetmetal part if you so desire.
Often the problem is that someone wants to "help you" by providing the flat state and you get to reverse engineer it. That's the only reason I mentioned the bend allowance calculation method.
