How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you calculate the area of a curcumfrence?
There's no such thing as the "area of a circumference", no matter how you spell it.A circumference is a length, representing the distance around a circle, and doesn'thave an area.If you know the circumference of a circle, and you call it 'C', then the area of the circle isC2 / (4 pi)
How do you convert circumference into square inches?
You can not CONVERT. Circumference is a measure of length and square inches is a measure of Area. However, if you know the circumference of a circle, you can FIND the area.for example:Circumference = pi x (2 x radius)solve for the radius = C/2pi,then Area = pi x r2 .You can do the same 'type' of calculation for Polygons, BUT you must know the lengths of the individual sides, not just the total circumference.
How do you find the circumference of a circle without knowing the area?
To find the circumference of a circle, you need only know the radius or diameter of the circle. The circumference of a circle is calculated as 2 x Pi x radius OR Pi x diameter. Pi is approximately 3.1415926.
How do you find the circumference of a circle of you know the area?
Divide the area by pi, which gives you the square of the radius. Take the square root and multiply by 2 pi and you have the circumference.
How do you fund the circumference of circle when you know the area?
You dived the area by the circumference of the circle.
How do you covert area into circumference?
Well, you can't really "convert" it, but I assumeyou want to calculate the circumference from the area. First, you need to know what figure you are talking about. For the specific case of a circle, I suggest you use the formula for the area of a circle, replace the known area, and solve for the radius. Once you have that, it is easy to calculate the circumference.
How do you convert circumference into square meter?
The circumference of a circle is a linear measurement - it is in ordinary metres. The area of a circle is a square measurement - it is in square metres. If you know the circumference of a circle (let's call it C), then the area (A) is calculated by first working out the radius (R) R = (C ÷ 2pi) A = (pi x R2)
How do you find the diameter of a circle in the terms of pi?
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
How do you calculate the area of a circle if you know the circumference?
By dividing its circumference by 2*pi will give the radius of the circle and its area = pi*radius2
How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you find the area of a circle if the circumference is 10?
We know that the area of a circle is pi * r2. We also know that the circumference of a circle is pi * d. Therefore, when you know the circumference of a circle and want to know the area, divide the circumference by pi to give you the diameter of the circle, divide the diameter by 2 to give you the radius, square the radius and then multiply by pi to get the area. So, 10/pi = 3.183. 3.183/2 = 1.5915. 1.59152 = 2.533 2.533 * pi = 7.958 to 3 decimal places. The area of your circle is therefore 7.958cm2.

How do you find the circumference of a circle when you know the area?
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).
How do you convert circumference into square inches?
You can not CONVERT. Circumference is a measure of length and square inches is a measure of Area. However, if you know the circumference of a circle, you can FIND the area.for example:Circumference = pi x (2 x radius)solve for the radius = C/2pi,then Area = pi x r2 .You can do the same 'type' of calculation for Polygons, BUT you must know the lengths of the individual sides, not just the total circumference.
How do you find the area of a circle when you already know the circumference?
radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi
How do you find the circumference of a circle without knowing the area?
To find the circumference of a circle, you need only know the radius or diameter of the circle. The circumference of a circle is calculated as 2 x Pi x radius OR Pi x diameter. Pi is approximately 3.1415926.
