If you are talking about "pi", the math constant related to circles, it is exactly 3.14159265358979. Most people use the approximation of 3.14 in calculating the area of a circle, the circumference, or the volume of a sphere. For very rough approximations, use 3. For example, the circumference of a circle is "pi" x diameter. So a 24-inch bike tire is about 72 inches around. The area of a circle is "pi" x radius squared. So a 10-inch Pizza gives you about 75 square inches to eat.

Who approxinnate the value of pie?
Everybody who gives a numerical answer to a sum involving π. The exact value cannot be calculated and so approximations must be used.
What is the approximations for pi?
3.14 and 3.14159 are two commonly used decimal approximations. In ratio form, 22/7 is often used.
What are the disadvantages of sampling?
You do not have all the information and so your conclusions are based on approximations.
Define pie and history of pie?
pie is a delicious desert.
How do you find the zeros?
Solve the equation - by whatever means available to you: factorising, graphical, numerical approximations, etc.
