If a circle has a circumference of 18pi, the radius is 9.
The circumference of a circle if the radius is 18 is: 113i have the same question and its multiple choice and none of the choices say 113! :((
The radius of a circle whose circumference is 36 pi (113.1) is: 18 (circumference divided by Pi divided by 2 = radius)
18/(2*pi) = a radius of about 113.09
Circumference of a circle: 2*pi*radius or diameter*pi
The circumference of a circle is calculated using the formula 2πr, where r is the radius. In this case, with a radius of 18 meters, the circumference would be 2 x π x 18 = 36π meters.
Circumference = 2Π• radius 2Π•9 = (18×Π)"≈ 56.5"
Circumference = 36*pi
A circle with a radius of 9 inches has a circumference of 56.55 inches and a diameter of 18 inches.
A circle with a radius of 18 inches has a circumference of 113.097 inches.
The radius is 18.
Radius of circle: 18/2pi = 2.865 inches rounded to 3 decimal places
