Circumference = 2*pi*rRadius = diameter/2r = 20 cm/2 = 10 cm-------------------------Circumference = 2*pi(10 cm)= 63 centimeters===========
Diameter in cm = circumference/pi
Circumference = pi * diameter ---> Diameter = Circumference / pi. Radius = Diameter / 2.Taking pi approx 3.14: Dia = 31.4 cm / 3.14 = 10.0 cm. Radius = 10.0 cm /2 = 5.00 cm.
A circle with a radius (d/2) of 15 cm has a circumference of 94.2 cm
Circumference = πd diameter = 2 x radius
Circumference = 2*pi*rRadius = diameter/2r = 20 cm/2 = 10 cm-------------------------Circumference = 2*pi(10 cm)= 63 centimeters===========
Circumference of a circle in cm = diameter*pi or 2*pi*radius
Circumference of circle in cm: 2 times pi
2pi cm
Diameter in cm = circumference/pi
Circumference of a circle in cm = 2*pi*radius or diameter*pi
Circumference: 2*pi = 6.283 cm to 3 decimal places
The diameter of a circle when the circumference is 35 cm is: 11.14 cm (circumference divided by Pi = diameter).
The diameter of a circle that has a 33 cm circumference is: 10.5 cm (circumference divided by pi = diameter).
Circumference = pi * diameter ---> Diameter = Circumference / pi. Radius = Diameter / 2.Taking pi approx 3.14: Dia = 31.4 cm / 3.14 = 10.0 cm. Radius = 10.0 cm /2 = 5.00 cm.
Well, darling, if the circumference is 27 cm, then we can use the formula C = πd to find the diameter. Just plug in 27 for C and solve for d. So, the diameter would be 8.59 cm. Hope that helps, sugar!
