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 perimeter if you already know the circumference of a circle?
The circumference of a circle is the length of the circle's perimeter.
