Using the offset tool, (O) we can select a distance or use points already on the drawing, then click on the selected line you want to offset.

make sure to check the setting. Press Ctrl and right click, select all settings exept the ‘nearest’ tool.

The first circle offset here are done using the measurement of the lines, the circles further out are the measurements that I have typed in.

Finding the centre point, the offset is then 800. Use trim tool to trim the lines at the end.
