## Step 2: Diameter

The distance around a circle is called the circumference. The distance across a circle through the center is called the diameter. is the ratio of the circumference of a circle to the diameter. Thus, for any circle, if you divide the circumference by the diameter, you get a value close to . The picture I have is the relationship, the numbers expressed is the formula:

Where C is circumference and D is diameter. You can test this formula at home with a round dinner plate. If you measure the circumference and the diameter of the plate and then divide C by D, your quotient should come close to Pi . Another way to write this formula is: C = Pi * D where * means multiply. This second formula is commonly used in problems where the diameter is given and the circumference is not known (see the examples below).
youre spelling is off. its Pi not Pie. you cant eat numbers.
If numbers were food then all my math classes would be very simple.
Ok the e's in pie have been treminated! ill be back. but they wont.
Not me. People have already posted alot of ones on the other things already. I just so happened to get mine in quick or maby even first. You should submit one.
What's next? Are going to see postings about multiplication table? I thought this site is for more sophisticated stuff...
