Insert the radius:
Simplify pi:
Simplify multiplication:
The circumference of the circles is 62.8. Now find the perimeter of the exposed squares with side length 10. There are 4 exposed sides, which equals one square. Find the perimeter:
Add the perimeter of the circle and the square together:
Now see which of the options gives you the perimeter:
