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 without knowing the radius and area?
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.
How do you find the area of a circle knowing only the circumference?
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.
What is the circumference of a table if the area is 28.26?
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.
What is is circumference of a circle is 6.28. What is the area of the circle?
If the circumference of a circle is 6.28 then its area is about 3.138 square units
How do you calculate area of circle without radius?
Well, what you do is you would find the circumference, or the distance around the circle.
How do you find the area of a circle without knowing the radius?
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.

How do you find area of circle without pi?
Area of a circle without pi = (circumference/diameter)*radius2
How do you get the circumference of a circle knowing the area?
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
How do you fund the circumference of circle when you know the area?
You dived the area by the circumference of the circle.
Is the Area of a circle and circumference of a circle have the same thing?
No,Circumference is like the perimiter and Area is the whole circle.
What is is circumference of a circle is 6.28. What is the area of the circle?
If the circumference of a circle is 6.28 then its area is about 3.138 square units
How do you calculate area of circle without radius?
Well, what you do is you would find the circumference, or the distance around the circle.
Is the circumference and area of a circle the same?
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.
How does knowing the formula for the circumference of a circle helps you develop the formula for the area of a 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.
