What is a proportional ratio?
In mathematics, two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other.
How would you find the radius of a circle with a circle with a circumference of 68cm?
First, divide the circumference by Pi (about 3.1416): 68 / 3.1416 = 21.65 cm. This is the diameter. Now, divide the diameter by two to get the radius: 21.65 / 2 = 10.825 cm.The radius is: 10.825 cmNote: The result will vary slightly depending on the value you use for Pi
