The formula for the circumference (C) of a circle is C = 2πr where r is the radius.
But, the diameter (D) of a circle is twice the radius so this formula can be written C = πD.
C = π x 13 = 40.841 cm (3dp)

What is the diameter of a 12cm circle?
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
If a circle has a circumference of 8 what is the diameter?
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).

What is the radius and diameter of circle area 530.66cm2?
Radius = about 13cm Diameter = about 26cm
How do you get diameter from circumference?
Circumference is Pi x Diameter so do Circumference divided by Pi to get the diameter :)
What is the circumference of a circle with a radius of 13cm?
It is: 2*pi*13 = 81.681 cm
How do you figure out diameter and circumference?
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
How do you find the diameter from the circumference?
Diameter = Circumference/pi
If you have your circumference how do you find the diameter?
diameter = circumference/pi
What is the diameter of a 12cm circle?
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
