to find the diameter of a circle when you only have the circomference you: divide the circomference by pi (approx. 3.14)
a circomference
6.843 cm
It is: 2*pi*radius or pi*diameter
a centimeter
7*pie=21.99114
20 (cm) 8 inches
Circumference of a circle = 2*pi*radius or pi*diameter
circumference = 2*pi*radius or pi*diameter
circomference of a circle = pi*diameter = pi*14
the answer is 21. the circomference is 3 times the diameter. so 7 times 3 = 21
