Okay, We have asked to d'oh Question 26 and we need to figure out there asking us what the circumference is in terms of pie. So they give you the equation. I have this. Okay, so we know that the equation of a circle is going to be like the standard equation squared. Plus why, minus b squared equals the radio radius squared. So, looking at the equation that gave us we can tell that the radius squared is gonna be nine. So the radius, the square root of nine is going to be three. So that's gonna be three units. Circumference is two pi r. So we're gonna take two times the pi times, the three, and it's gonna be six pie units. That's your answer.

The number 2 is also the smallest & first prime number (since every other even number is divisible by two).

If you write pi (to the first two decimal places of 3.14) backwards, in big, block letters it actually reads "PIE".
