The ratio of the circumference to the radius of the circle is 2 times pi
The circumference of a circle is 2*pi*radius or pi*diameter
The circumference of a circle is equal to its diameter times pi. This is also equal to two times its radius times pi.
Circumference of the circle is: 2 times pi
The circumference of a circle is equal to the radius times 2*pi. 2*pi*R where R is the radius.
Take "pi" times the diameter of the circle. Pi = 3.14159 (ALWAYS) If circle has a diameter of 10cm, circumference 31.41cm If circle has a radius of 2inches, the circumference is 12.57 inches. (radius = 2, diameter = 4)
The ratio of the circumference to the radius of the circle is 2 times pi
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.
It is: circumference/radius = 2*pi
The circumference of a circle is 2*pi*radius or pi*diameter
area: pi times radius squared circumference: pi times radius
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 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 a circle is two times pi times the 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 equation for the circumference of a circle is pi times radius squared.
Circumference of the circle is: 2 times pi
