9. Circumference equals 2 times Pi times the radius. C=2(pi)r. "r" for radius. So if your circumference is 18 times pi, then you do 18 divided by 2, which gives you a radius of 9.
If radius equals 2.25 meters the circumference is: 14.1 meters.
If a circle's radius is 2.4 its circumference is: 15.1
The circumference of a circle if the radius is 12 equals about 75.4
The radius is 10.5
Circumference = 2*pi*radius = 189.75 units of length.
Circumference equals pi times the diameter. Since the diameter is twice the length of the radius, the circumference is 6 times pi, or about 18.84 feet.
If radius equals 2.25 meters the circumference is: 14.1 meters.
If a circle's radius is 2.4 its circumference is: 15.1
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
The circumference of a circle if the radius is 12 equals about 75.4
2r(pi)=C where C is circumference. Therefore the radius equals C/2(pi)
The radius is 10.5
Circumference = 2*pi*radius = 189.75 units of length.
Circumference = (pi) x (diameter) Diameter = 2 x radius
The circumference = 18.8 cm
The circumference of a circle when the radius is 25 feet equals about 157.08 feet.
It depends on what "this measurement" refers to: the radius, circumference, length of arc with a known angle.
