6 0

Answer:

Step-by-step explanation: Plug the radius into the formula 2 $\pi$ r so first you multiply the radius by 2, giving you 6 $\pi$ , next, multiply 6 by pi(3.14) and you will end up with 18.849, then you round up and end up with 18.85

How is 1 over 9 a rational number?

Kruka [31]

Answer:

Because 1/9 is a fraction with integers meaning it is a fraction with whole numbers.

Step-by-step explanation:

Any number that can be written as a fraction with integers is called a rational number. For example, 17 and −34 are rational numbers. (Note that there is more than one way to write the same rational number as a ratio of integers. For example, 17 and 214 represent the same rational number.)

Hope this helps
