Circle and Square Area Concepts

The video tutorial explains how to find the areas of a square and a circle, and then determine the area of the region inside the square but outside the circle. It begins by calculating the area of the square using the side length, which is equal to the circle's diameter. Next, it calculates the area of the circle using its radius, derived from the diameter. Finally, it finds the area of the yellow shaded region by subtracting the circle's area from the square's area, providing both exact and approximate values.

What is the diameter of the circle given in the problem?

• 8 miles

• 32 miles

• 4 miles

• 16 miles

How is the side length of the square related to the circle?

• It is twice the radius of the circle.

• It is equal to the diameter of the circle.

• It is equal to the radius of the circle.

• It is half the diameter of the circle.
