area = π x radius2
⇒ radius = √(area ÷ π)
circumference = 2π x radius
⇒ circumference = 2π x √(area ÷ π)
⇒ circumference = √(4π2 x area ÷ π)
⇒ circumference = √(4π x area)
So knowing the area, the circumference can be calculated by taking the square root of the area multiplied by 4 times π
Example: What is the circumference of a circle with area 78.54cm2
Circumference = √(4π x area) = √(4π x 78.54cm2) ~= 31.42cm
If the table is circular, then its circumference is 18.845 (rounded) If it's not a circle, then the circumference can't be calculated knowing only the area.
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
The area of a circle with a circumference of 9.42 is about 7.06.
You dived the area by the circumference of the circle.
If circumference is C then the radius is C/(2*pi) and then area = pi*r2 = C2/(4*pi)
No,Circumference is like the perimiter and Area is the whole circle.
If the circumference of a circle is 6.28 then its area is about 3.138 square units
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.
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
The circumference would be 50.265
You will have to measure some part of the circle. As long as you have absolutely no information about a circle, you can't do any calculations.
