If the diameter of a circle is 2 inches the circumference is: about 6.283 inches (c = d x pi).
A circle with a radius of 16 inches (32/2) has a circumference of 100.53 inches.
You need to specify what the '8 inches' represents!!! Is it radius, diameter, or all the way round (circumference).
11.5/pi, almost exactly 3 and 2/3 inches
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
If the radius is 2 then the diameter is 2*2 = 4 inches and the circumference is about 12.6 inches and not 15 inches
A circle with a radius of 16 inches (32/2) has a circumference of 100.53 inches.
Diameter of a circle = 2*radius Diameter of a circle = circumference/pi
A circle with a radius (d/2) of 39.25 inches has a circumference of 246.6 inches.
Circumference of a circle = 2*pi*radius or diameter*pi
Circumference of the circle: 4 times pi in inches
Circumference of a circle = 2*pi*radius or diameter*pi
Circumference of a circle in inches = 2*radius*pi or diameter*pi Both radius and diameter must be in inches
If its diameter is 10 inches then its circumference is: diameter*pi If its radius is 10 inches then its circumference is: 2*pi*10
Circumference of a circle = pi*diameter or 2*pi*radius Circumference = 11.62389282 inches
Circumference = pi*d = 169.65 inches (to 2 dp)
Circumference of a circle: 2*pi*radius or pi*diameter
The circumferecne of a circle with diameter d is pi*d So diameter = circumference / pi = 36/pi = 11.46 inches. Radius = diameter/2 = 5.73 inches.
