It's possible, the circle can also be drawn with the pen. Inkscape's pen has Spiro path mode in the option bar. Select it to make approximately right circles:
This needed 3 clicks. One in the midpoint, the 2nd to 11 o'clock and the last one to close the curve at 5 o'clock.
Duplicate the result (=Ctrl+D). Flip it horizontally.
Set all point snaps on, also the midpoint snap.
Set for the pen the normal Bezier curve mode ON. Draw the V shown in the next image from 11 to center to 1 o'clock. It needs 3 clicks and one right click to stop the drawing.
Select the V and one of the circles. Apply Path > Division and drag the slice apart:
Here's another way - just for fun and knowing better the tools. It also needs point snaps = ON
You have a circle. Draw a line with the pen across the circle. Hold Ctrl to get it horizontal, if that's needed. Draw a line which starts from the centerpoint. Its direction and length can be arbitary, but I drew a radius to the crossing (=blue). You need the line only to remember the center. To get it right you must have centerpoint snap =ON.
Select the horizontal line and the circle. Separate the circle segment by applying Path > Division, remove the bottom part.
Double-click the horizontal line somewhere with the node tool to create a new node. Drag that node to the center. Delete the extra line (=blue).
BTW. No need to divide the circle. You can as well convert it to path (=Path > Object to Path) and insert with the node tool new nodes to the ends of the wanted slice edge. Then you delete the unnecessary nodes of the circle and shorten the handles, You have the same circle segment as you got by dividing with a line.
