To find the area of the shaded region, subtract the area of the small circles from the area of the large circle. Each small circle has a diameter of 2, so each has a radius of 1. Plug this value into the formula for the area of a circle:A_((small circle))=π r^2=π(1^2)...
There's no way to figure out the area of the shaded region directly, but you can figure out the area of the non-shaped region and subtract. Since the radius of the circle is 5, you know that the area of the circle is 25π. Subtract that from the area of the square, 100, to g...
