Best Answer

The formula given is schools is circumfrence=2(pi)radius. But since I am a rebel, I use diameter times pi. This works since diameter equals 2 times radius. If you don't know, pi exactly equals 22 divided by 7. Or 3.14159.....as for an example, if you have a circle with diameter of 2, then you plug it in the formula. Then get your answer or 2(pi).

Multiplying the diameter by pi (approx 3.1416) will give you the circumference of the circle.

Divide the circumference by the value of Pi - that will give you the diameter.

Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)

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

it depends on what the radius is if they give you one

Doubling the radius will give the diameter and times this by pi will give the circumference of the circle.

Divide the circumference by 2*pi which then will give you the radius and use pi*radius2 to find the area of the circle

You divide the circumference by Pi (about 3.1416). This gives you the diameter. Divide the diameter by two to get the radius.

You multiply the diameter by pi, which is approximately 3.1416.

Divide the circumference by 2*pi which will give the value of the radius. Then use p*radius2 to find the area of the circle.

Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.

Divide the circumference by 2*pi will give the radius of the circle.

The circumference of a circle is the length around it.

Will give the circumference of half of the circle.

They would have to give you enough information to eventually get the diameter. If they gave you the area of a circle and asked for the circumference, you can determine the radius, and from the radius the diameter, and then the circumference. If they said "What is the circumference if the area of a circle is 36pi?" Area of a circle is pi*r2, which would give us a value for r = 6 Diameter is 2*r, or = 12. Circumference is d*pi, or 12pi

well you can divide the circumference by pi (3.14) and it will always give you the diameter or you could measure it.

Divide the circumference by Pi (3.14159), and that will give you the diameter. Divide that number by 2 to find the radius.

Divide the circumference by pi, and that will give you the diameter.

the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi

The circumference of a circle is a distance. It's the distance you would drive to go around the circle. If you straighten it out, you have a line. It's a simple length, and doesn't involve squares or cubes. If they give you the radius of a circle and u want to find the circumference u have to do 2* TT* r and if they give u the diameter u do TT*d

By dividing the circumference by 2*pi will give you the radius and twice the radius gives you the diameter.

Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.

Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
