Draw an arc (or cicrle) or what ever it is you want to curve the text path around. Insert the text. Click on the Arrow (pointer) tool, and select your text, hold the shift key, while selecting your curve.
Go to the top menus, chose the Text box -> Fit text to path.
This should now "snap" the Text to the curve. You can play with the attributes to adjust the text "On", "Below", or "centered" to the line, as well as justification and letter orientation.
Now, if you don't want the circle in the picture, you just want the text floating free in space in a nice arc, click anywhere off of the two items (the arc and the text) to de-select all objects. Now click on JUST THE CIRCLE. Hit the Delete button, the circle goes away, and the text stays as you modified it.
You should be able to do a search in the interactive help, as well as check out the tutorials...I think this is covered step-by-step in both....
HTH,
