To calculate the circumference multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation.

3.22x 2 = 6.44

6.44x π= 20.23185668911827

rounded to the nearest ten: 20.2

How do you know if a number is rational or irrational

Kay [80]

A rational number is a number that is not repeating. So a rational number can be 5 or 2.3314. But Pi is irrational. So is 1/3 and 2/3 because in decimal form they are repeating. Which means they will go on forever which makes them irrational.
