the equation for the area of a circle is π(pi)r² so pi times radius squared. the side length of the square will be your diameter, so divide that by 2 to get the radius and plug that into your formula, and you will have the are of the circle. hope that helped.

To find the area of a circle inscribed in a square, you can use the formula for the area of a circle (πr^2) and the properties of a square (all sides equal). Since the diameter of the circle is equal to a side of the square, you can find the radius of the circle by halving the side length of the square. Then, plug the radius value into the area of a circle formula to find the area.
The area of the circle is πr^2 = (π(10/2)^2) = 25π square inches. The area of the square is 10^2 = 100 square inches. The area of the region inside the square and outside the circle is 100 - 25π = 21.46 square inches.
The area visible to the forest ranger from a fire tower is a circle with a radius of 12 miles. The formula to calculate the area of a circle is πr^2. Therefore, the ranger can see approximately 452.4 square miles.
A circle with a diameter of 1 metre has an area of pi/4 square metres.
The area of a circle is calculated using the formula A = πr^2. Given that the circumference of the circle is 50π, we can determine the radius using the formula C = 2πr, where C is the circumference. So, 50π = 2πr. Solving for r gives us the radius as 25. The area of the circle with radius 25 is then A = π(25)^2 = 625π.
To find the circumference of a circle when you know the area, you first need to find the radius of the circle using the formula for the area (area = πr^2). Once you have the radius, you can calculate the circumference using the formula for the circumference (circumference = 2πr).
