Answer
From where you are now you can just make a circular guide.
- draw a circle with a size that will be the new starting point for your lines;
- make it a guide (View > Guides > Make Guides or CMD+5 / CTRL+5 for Windows);
- select the anchors (the ones near the center) using the Lasso tool (Q), for example
- with smart guides enabled, scale your lines (S) and drag until they intersect with the guide
