the equation to find circumference is C=2*pi*radius so when you have a radius of 18 inches, C=113.097
18/(2*pi) = a radius of about 113.09
Circumference = 2Π• radius 2Π•9 = (18×Π)"≈ 56.5"
If a circle has a circumference of 18pi, the radius is 9.
The two that have a circumference of 18 pie are a radius of 9 units and a diameter of 18 units.
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.
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! :((
Circumference = π x diameter = π x 2 x radius → Those with a diameter of 18 units which is a radius of 9 units have a circumference of 18 π
The radius of a circle whose circumference is 36 pi (113.1) is: 18 (circumference divided by Pi divided by 2 = radius)
Circumference = 36*pi
If the radius is 18 feet - then the diameter is 36 feet. The circumference measurement is irrelevant !
The radius is 18.
