How do you find the area of a circle if you know the circumference?

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 ...

You dived the area by the circumference of the circle.

Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared ...

If you know the area, you can find the radius --> A = (pi) * r^2 If you have the radius, you can find the circumference --> C = (pi) * 2 * r ...

If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...) ...

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 =...

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. ...

Divide the known circumference by pi to find the diameter of the circle.

It depends on what you want to convert the area of the circle into.

By dividing its circumference by 2*pi will give the radius of the circle and its area = pi*radius2...

radius = circumference/(2*pi) area = pi*radius2 So Area in terms of Circumference is A = pi [C/2pi]2 or (circumference)2/4 pi ...

If you have the circumference- You have to divide the circumference by 2*Pi If you know the diameter the radius is simply half the diameter. If you know the area of a circle, the radius can be found using the formula : R = √A/π where: A is the area of the circle and π is Pi, approximately 3.142. ...

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. ...

The circumference of a circle is the length of the circle's perimeter.

You can find the circumference of a circle if you know its area by using the formulas for area and circumference. First, use the formula for area: A = pi r2. Replace A with the number for the area. Solve the formula for r, the radius of the circle, dividing A by pi and taking the square root of the answer. Once you have the number for r, the radius of the circle, plug that value in place of r in...

circumference/pi = diameter

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't have an area. If you know the circumference of a circle, and you call it 'C', then the area of the circle is C2 / (4 pi) ...

circumference of a circle = pi * diameter.

To find the diameter of a circle divide its circumference by pi

In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44? ...

We know that 2πr=circumference (or πxdiameter) So simply re-arrange the equation to get r=circumference/2π Now that you have r, πr^2=area ...

Pi is related to the area of a circle because it just is. It is closely related to it in math, and to find the circumference (PI 3.14), you must know the area or the diameter. ...

The diameter of a circle is directly proportionate to the circumference. You can find the diameter of a circle by dividing the circumference by the value of Pi (3.14) OR you can find the circumference by multiplying Pi by the diameter. it is a line that halves a circle ...

Diameter = circumference/pi

It's important to know the formulas for all these characteristics of circles, and to recognize what they have in common. Area of a circle = πr2 Circumference of a circle = 2πr or dπ Where in the above equations r represents radius, and d is diameter (2r). Both these equations have r in them. Find the radius using the circumference equation, and then plug it into the equation for Area ...
