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! :((

C = 113

18 yards

Circ = 2 pi r = 60pi = 60 x 355/113 = 188.5" to one significant figure

If the radius is 18 feet - then the diameter is 36 feet. The circumference measurement is irrelevant !

Take pi as 355/113, then area = 355 x 121/113 = 380.13 sq in. and circumference = 22 x 355/113 = 69.12 in.

The diameter of a circle that has a circumference of 113 mm is about 35.97 mm

36pi or 113

Radius of circle: 37.68/2pi = 5.996958256 units Area of circle: pi*5.996958256^2 = 112.9826266935 or about 113 square units

The circumference C of a circle with radius R is C = 2*pi*R pi = 3.1416... R = 18 Using a calculator: C = 113 inches This is the length of track of an HO model train laid out with eight curved sections to form a circle of radius 18 inches, such as around a christmas tree.

113/pi feet ie less than half an inch under 36 ft

C = 113 inches.
