To calculate the area of a circle, you can use the formula A = πr^2, where A is the area and r is the radius of the circle. Simply square the radius, multiply it by π (approximately 3.14159), and you will have the area of the circle.
The square footage of a 24-foot circle is approximately 452.39 square feet. You can calculate this by using the formula for the area of a circle which is A = πr^2, where r is the radius of the circle (which in this case would be half of the diameter, so 12 feet).
Your question doesn't make sense. The area of a circle is Pi (approximately 3.14) times the RADIUS squared. An example would be a circle with a diameter of 6 inches and thus the circle would have a radius of 3 inches. Three squared (3 times 3) is 9, and 9 times Pi is approximately 28.3 square inches.
To calculate the area of an irregular pentagon, you can divide it into shapes with known formulas (such as triangles and rectangles) and then sum their areas. Alternatively, you can use a formula specifically designed for irregular pentagons, such as Heron's formula if you know all the side lengths. You may also use trigonometry to calculate the area if you know certain angles and side lengths within the pentagon.
A circle is a two-dimensional shape with all points equidistant from its center, forming a closed curve. It has no angles, sides, or vertices. Its main characteristics include radius, diameter, circumference, and area.
Radius of circle times 2, multiply that by pi (3.14 for easyish reckoning), and that's the circumference of a circle. The circumference of an object is the distance around the outside or perimeter. Different formulae are used to calculate this depending on the shape.
