Tacircle:

Shade some circles that are centered on grid vertices and have integer radius length. Circles must be contained entirely within the grid and cannot overlap squares with clues. Numbers represent the combined area of all circles that touch the corners of the clue's square, divided by pi. Numberless clues must touch at least one circle. Circles may be adjacent but there must be only one unshaded region.
