In a 7 by 7 grid, each of the 49 small squares measures 1 cm by 1 cm and is shaded. Seven unshaded circles and four unshaded squares are placed on top of the grid as shown. The area of the visible shaded region can be written in the form $A-B\pi-C$ square cm, where the $C$ is the area covered by the smaller unshaded squares. What is the value $A+B+C$?

Assume:
- Five circles have a diameter of 1 cm each.
- Two circles have a diameter of 2 cm each.
- Four squares, each with a side length of 0.5 cm, are placed unshaded.
