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 = (pi) x (diameter) Diameter = 2 x radius
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 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 = (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.
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.
assume you mean the radius is 5.25. so circumference is 2x pi x radius or approx 32.99 yd
the equation to find circumference is C=2*pi*radius so when you have a radius of 18 inches, C=113.097
Circumference equals pi times radius squared, so 3.14x36=113.04 meters.
