[tex] \pi [/tex] is an irrational number i.e. it cannot be written in the form of [tex] \frac{p}{q} [/tex] where p and q are integers and q is never equal to 0.
By multiples of [tex] \pi [/tex], we can write like:
1[tex] \pi [/tex] = [tex] \pi [/tex] = 3.14
2[tex] \pi [/tex] = 2*3.14 = 6.28
3[tex] \pi [/tex] = 3*3.14 = 9.42
In the same way, any integer n when multiplied by [tex] \pi [/tex], is a multiple of [tex] \pi [/tex]
