But what we did do is study for our test tomorrow.

Here are some things to know to be ready for the test.

d=2r

This means diameter equals radius x 2.

This basically means that the diameter is twice the radius.

C=πd

This is the formula to find out the circumference. The formula stands for Circumference equals Pi times diameter

This means that the diameter times the Pi will give you a circumference.

The Pi is 3.14159265

But for the test, we will use the shortened version-3.14.

C=2πr

This is basically the first two formulas combined. You multiply the radius by 2 and multiply it by π (3.14)

And we also got a study quiz.

This is what it looked like:

Diameter | Check | Radius |
---|---|---|

10 | 5 |

The middle "check" part is for you to check your answers later to see if you got the answers right.

You can also do this in home without the sheet.

I hope every passes the test.

Edit: I keep forgetting, I pick Brayden to do the next scribepost.
