The Pi Approximation Day is celebrated on July 22 as the date 22/7 marks the approximate value of Pi (22.7). However, Pi day is celebrated on March 14, as the date marks the actual value of Pi - 3.14.

For some, today (July 22) is Pi Approximation Day, but for some others, it is March 14. Pi is the ratio of the circumference of any circle to the diameter of that circle. Greek letter π was first used ...

The area \(A\) of a square of side length \(s\) is \(A=s^2\text{.}\) Suppose \(s\) increases by an amount \(\Delta s=ds\text{.}\) Draw a square and then illustrate ...

In simple terms, approximation means replacing actual numbers with their nearby simple values to make calculations faster. For example, instead of multiplying 19.9 with 5.1, you can take them as 20 ...
