The formula is the radius of the circle squared (multiplied by itself) times pi, which is a number that goes on forever and never repeats. Some people use 3.1415925, but it is most commonly considered as 3.14
This is most often written πr2 =Area of the circle where r is the radius of the circle. Using 3.14 as an approximation for π, we have Area=3.14 x r2

What is the area of a circle which has a radius equal to 1?
The area of a circle can be calculated using the formula pi*(radius^2). So in this case, the area of the circle will be pi*(1^2), which is equal to pi.
What is the formula for finding an area of a circle?
The area of a circle with a known radius can calculated using the following formula where r is the radius : A = Pi(r)2
How do you coculat area?
That depends on the area to be calculated and some examples are:- Area of a circle = pi*radius2 Area of a triangle = 0.5*base*height Area of a rectangle = base*height
How many square inches are in a 2 inch circle?
The phrase "two inch circle" implies that the circle's area has already been calculated as "two square inches". However, if you truly meant that the circle had a diameter of two inches, it's area would be pi. Alternatively, if you meant a radius of two inches, the area would be 4pi.
What is the area of a 2m circle?
Since you didn't state If the 2m was a diameter or radius, it will have to be calculated as If it were both: Diameter: Pi x D = Area of Circle 3.14 x 2m = 6.28 m² Radius: Pi x R² = Area of Circle 3.14 x 2m² = 3.14 x 4 = 12.56 m²
Help with math how do you get the area of a circle?
Area of a circle is calculated by A=2*p*r where A represents the circle's area and r is the radius of the circle.
What is An area of circle?
The area of a circle is the amount of space inside the circle. The area of a circle is calculated by multiplying pi(3.14159) by the radius squared.
Area of a circle with 6 meter radius?
The area of a circle is calculated as A = pi x r2
How do you calculate m2 of a circle?

What is the area of a circle that has a cm diameter?
The area of a circle is calculated from the formula Pi x r2 . A 1cm diameter circle has a radius of 0.5cm, thus it has an area of 0.785cm2
What is the area and perimeter of circle?
The area of the (inside) of a circle - the circle itself is a line with no area - is calculated by:pi * r2the perimeter - also called the circumference is the length around the circle and is calculated:2 * pi * rwhere "r" is the radius, the distance from the center to the edge of the circle and "pi" is the irrational number 3.14159....
Is there an association between the radius of a circle and the area of a circle.. please explain?
The radius of a circle and the area of a circle are directly proportionate. This is because the area of a circle is calculated by the formula: Area = pi * radius2. Since we are using the radius to find the area, there is an association between the two.
What is the area of a circle which has a radius equal to 1?
The area of a circle can be calculated using the formula pi*(radius^2). So in this case, the area of the circle will be pi*(1^2), which is equal to pi.
What is the formula for finding an area of a circle?
The area of a circle with a known radius can calculated using the following formula where r is the radius : A = Pi(r)2
How do find the area in math?
It depends on what you are trying to find the area of. The area of a rectangle is calculated by multiplying the length of the rectangle times the width of the rectangle. The area of a circle is calculated by multiplying pi times the radius of the circle squared. See the Related Links for more information on calculating area.
Is the area of a circle the same as the circumference of a circle?
No. The circumference is the distance round the outer edge of the circle, calculkated as 2 x pi x the radius.The area is calculated as pi x the square of the radius.
What is the Amount of space a circle takes up?
The amount of space a circle takes up is determined by its area, which can be calculated using the formula A = π * r^2, where r is the radius of the circle.
