Pi is not a natural number.Wholenumbers: 0,1,2,3, …. Pi is not awholenumber. Rational number: The numberswhich canbe expressed in the form P/Q where P & Q are integers& Qin not zero.

Similarly, you may ask, is 3.14 a natural number?

The number pi, denoted π, is awell-knownirrational number that is generally known to havevalue3.14. However, 3.14 is actually thenumberπ rounded to two decimal places, and is not thetrue value ofπ. Therefore, there is often some confusion as towhether3.14 is a rational or anirrationalnumber.

Also know, is Pi a real number?

Pi is an irrational number, whichmeansthat it is a real number that cannot be expressed byasimple fraction. That's because pi is whatmathematicianscall an "infinite decimal" — after the decimalpoint, thedigits go on forever and ever.

How is the value of pi derived?

A Brief History of Pi (π) The ancient Babylonians calculated the area ofacircle by taking 3 times the square of its radius, which gaveavalue of pi = 3. One Babylonian tablet (ca.1900–1680BC) indicates a value of 3.125 for π,which is a closerapproximation.

## Is 7 a rational number?

Every integer is a rational number, sinceeachinteger n can be written in the form n/1. For example 5 = 5/1andthus 5 is a rational number. However, numberslike1/2, 45454737/2424242, and -3/7 are alsorational,since they are fractions whose numerator anddenominator areintegers.
