A circle of radius is inscribed in a square. Find the area of the shaded region.
Answer: The area of the shaded region is .
Step-by-step solution
Step 1: Determine the side of the square
When a circle is inscribed in a square, the diameter of the circle is equal to the side length of the square. Since the radius is given as , the diameter will be .
Step 2: Calculate the area of the square
Now that we know the side length of the square is , we can calculate its area using the formula for the area of a square, which is side squared.
Step 3: Calculate the area of the circle
Next, we calculate the area of the inscribed circle using the formula . We are given the radius and instructed to use .
Step 4: Calculate the area of the shaded region
The shaded region is the area of the square minus the area of the circle. We subtract the calculated area of the circle from the area of the square to find the final answer.
