circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
3 times
The circumference of a circle if its radius is 3 is about 18.85
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 radius is 3.
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
Circumference is equal to 2 times pi times the radius. The radius is half the diameter, so pi times the diameter is also the circumference. In this case, the diameter is 3 meters so 3 times pi equals 9.42 So the circumference is about 9.42 meters.
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
3 times
(radius+radius) times pi
The circumference of a circle if its radius is 3 is about 18.85
to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
Radius times 2. then, that times Pi
3.14 times the radius times 2
Circumference = pi (3.14) times the diameter (radius times two) Area = pi (3.14) times the radius squared
A circle with a radius of 3 units has a circumference of 18.85 units.
