A circle with a radius of 8 units has a circumference of 50.3 units.
C = 69.115 cm
Circumference=2Pir so 64 is Pixr and the radius is 64/Pi
A circle with a diameter of 8 inches has a radius (not raduis) of 4 inches.
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
11cm * pi 34.5575192 centimeters
A radius (not raduis) of 15 units implies a circumference of 94 units.
A circumference of 34.6 cm
Circumference = 2*pi*radius (not raduis) = 19 cm, approx.
A circle with a radius of 8 units has a circumference of 50.3 units.
C = about 12.57
Divide the circumference by 2pi
Radius = circumference/pi
Circumference of a circle = 2*pi*radius
Circumference of a circle: 2 x pi x radius.
circumference = 2*pi*9 inches
C = 69.115 cm
