Pi x R squared. = area of a 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 find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.
A circle is a shape where every point along the edge is equidistant from a point at the center. The distance from the center to the edge is called the radius. The distance across the widest point of a circle is called the diameter, and it is always equal to the radius x 2. The distance around the circle is called the circumference, and is equal to the diameter x 2 x pi (3.14 and so on). The area of the circle is equal to the radius squared (multiplied by itself) x pi. hello Richard paskeman
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.
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
To calculate the area of a circle use this formula: pi x r2.
the area of the circle is Pi X Radius squared
The area of a circle is: pi times radius squared
The formula used to calculate the area of a circle is A r2, where A represents the area and r is the radius of the circle.

A circle is two dimensional, it has area but not volume.
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.

To calculate the are of a circle, use the formula area = pi x radius2.
The base of a cone is a circle. The area of a circle is found by multiplying the diameter by Pi.
you calculate the Area of the circle at the end of the Cylinder and then multiply it by the lenght to the second circle at the end of the cylinder Circle area= Radius*Radius* pi pi being 3.14159265
