How do you find the area of a circle with pi? You always have to measure the diameter or the distance on how long it is. From there you get the measurement and then you multiply it by pi and you get your answer. For example say you have a circle of about 3.25 inches in its diameter. You had to measure that in order to get  the inches and then you have to multiply it by pi in order to get the answer of 10.21. Of course, I rounded, but before we multiply we are going to have to round pi to 3.14 or you'll just get the longest of the numbers.
     Here is another example: If you have a circle of about 13 inches what would be the answer? Well all we would have to do is multiply 13 by 3.14, and we would get our answer of 40.82 inches in the circle's area. That is a simple easy way to find the area of a circle.
 
What are some things you should know about pi? Not pie as in the kind of eat but pi the one used in math. Pi is a symbol mostly everyone knows about, and there is competitions on Pi Day just to see who can memorize the most numbers of Pi. Pi is a number that goes on and on forever without stopping. All I know is that it starts out with 3.14159, usually the shortening for that number is 3.14 for in math problems you would use 3.14.
     There are some things that we could know more about Pi. Like how it's practically a number that repeats itself, because after a long set of numbers it''s like if the same numbers where there. Nobody knows for sure if anyone could memorize the whole number of pi, but that is why there are competitions to see who can memorize the most numbers of pi.
 
If we were to have the formula of y=mx+b how would we graph that? Well we would need an example, because we can't just make a line out of that formula because it doesn't have any numbers. So for an example we could use an equation like y=2x+12. Now that we have and equation we can see where the line would start and how the slope would be. The starting point would be 12 since b or the y-intercept is 12.
     We know that the equation would then start from twelve because it is the y-intercept. Then we would use m or the slope to find out how steep the line is. So we would start at 12 and count up to and then over one because if the number has to be like a fraction even though it doesn't have a number as the denominator there will always be a one on the bott
