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.
To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Square the circumference, then divide it by 4π to get the area.
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 of a circle is 6.28 then its area is about 3.138 square units
Well, what you do is you would find the circumference, or the distance around the circle.
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.

Area of a circle without pi = (circumference/diameter)*radius2
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
You dived the area by the circumference of the circle.
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
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.
Well, what you do is you would find the circumference, or the distance around the circle.
Circumference is: 2 × π × r (or π × d)Area is: π × r²I don't believe that one can really be said to help develop the other.
