Students could read and interpret a diagram to find the side length of a large square in terms of the radius of an inscribed circle. They could use Pythagorean theorem to find the length of the small square given the hypotenuse. Students could compare the ratios of the areas of circles and squares.
The perimeter of a square is given by the formula P = 4s, where s is the length of one side. The area of a square is given by the formula A = s^2, where s is the length of one side. Squares have equal angles of 90 degrees at each corner, making them ideal for creating right angles.

A square and a circle are both shapes with a well-defined center. Each shape only needs a single length to determine its size. For a square, we need a side length to determine the size. With this information, we can determine both the perimeter and area of a square. For a circle, we need a radius to determine the size. With this information, we can...
Remember that the perimeter of a shape is the path that completely surrounds the shape (no more and no less). We can calculate perimeter as a length in linear units (such as inches, feet, centimeters, meters, etc.) For a square with a side length of S, the perimeter is 4S. We get this result by adding up the four equal side lengths of a square: S +...
Remember that the area of a shape is the amount of space inside the boundary of the shape (no more and no less). We can calculate area in square units (such as square inches, square feet, square centimeters, square meters, etc.). These square units come from multiplying two dimensions (and thus two units) together. For a square with a side length o...
When you inscribe a square in a circle, you are finding the largest square that can fit inside of that circle. Another way to think of it is finding the smallest circle that will contain the square. You can see what this looks like in the diagram below. We can find the relationship between these two shapes as follows. Let R be the radius of the cir...

The formula for the area of a circle is: A = πr2, where r is the radius of the circle. To find the area of a circle, follow these simple steps: find the radius of the circle (the distance from one side to the center of the circle). It is the same as half of the diameter of the circle. square the radius (multiply the radius by itself)
The area of a circle is calculated using the formula A = πr², where r represents the radius. On the other hand, the area of a square is determined by A = s², where s represents the length of one side.
