can you explain pie to me i'm in y7 and want to get ahead!
Pie is a baked good with a crust made of flour and shortening. It's filled with fruit or meat and vegetables and baked in an oven.
Do you mean the mathematical term "pi?"

Here is a very simple way to explain it.
Consider any circle, the top of a coffee can or soup can will do.
Hold a string along the diameter of the can.
You will be able to fold that length around the can π times.
that is, three times and "a bit" left over.
that "bit left over" will be the decimal part of the value of π
or
Fold a string around a can and measure its length, that is called the circumference.
Measure the diameter of the can
Divide the circumference by the diameter, you will get an approximation of π
Of course! I'd be happy to explain pi to you. In mathematics, π (pronounced as "pi") is a special number that represents the ratio of a circle's circumference to its diameter. It is a constant value that is approximately equal to 3.14159. Pi is an irrational number, which means it goes on infinitely without repeating any pattern.
To understand pi better, you can follow these steps to calculate it using a circle:
1. Start with a circle: Draw a circle on a piece of paper or use a round object as a visual aid.
2. Measure the diameter: Take a ruler and measure the distance across the circle passing through its center. This is called the diameter.
3. Measure the circumference: Using the same ruler, measure the distance around the edge of the circle. This is called the circumference.
4. Divide the circumference by the diameter: Take the circumference and divide it by the diameter you measured. The result you find should be close to 3.14159, which is pi.
Pi shows up in many areas of mathematics and science, including geometry, trigonometry, and calculus. It is used to calculate the area and volume of circles, as well as in equations involving angles and waves.
Remember, pi is an important constant in mathematics, and its value helps us understand and solve various mathematical problems involving circles.
