The circumference of a circle is equal to its diameter times pi. This is also equal to two times its radius times pi.
Circumference = pi (3.14) times the diameter (radius times two) Area = pi (3.14) times the radius squared
Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14
circumference = 2 x π x radius ⇒ radius = circumference ÷ (2 x π) Divide the circumference by two times π (≈ 6.283).
well the circumference is equal to pi times the diameter, so all that you have to do is divide the circumference by pi to get the diameter. Then you divide the diameter by two to get the radius.
The circumference of a circle is two times pi times the radius.
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
the circumference of any circle is 2PIr or two times PI(3.14) times the radius (in this case, 16). do the math.
The circumference is ALL the way around the circle, while the radius is only HALF way into the middle of the circle. I'm guessing you meant "What is the relationship between the radius of a circle and its circumference?" Radius is half of the diameter of a circle, circumference is PI times diameter; therefore, the circumference is PI times two times radius.
The circumference of a circle is equal to its diameter times pi. This is also equal to two times its radius times pi.
The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.
The ratio of a circle's circumference to its area is called the reciprocal of half the radius. The ratio of the circumference to its radius is called two times pi.
Circumference = pi (3.14) times the diameter (radius times two) Area = pi (3.14) times the radius squared
Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
First, you do the radius of a circle times two. Then you multiply that times PI, which is 3.14.
The circumference is essentially the perimeter of the circle, or the distance around the circle. To calculate the circumference of a circle, use the formula C = 2 * pi * r. Circumference = two times pi times the radius of the circle.
