lela to determine the largest of the following real numbers

In ths question, we have a set of numbers, and we have to determine the largest real number
[tex]\sqrt{30}-5 , 3 \sqrt{14}-6 , 6.03, 2 \pi[/tex]
First we need to convert each of them in decimal form. That is
[tex]\sqrt{30}-5 =0.477 \\ 3 \sqrt{14}-6 = 5.22 \\ 6.03=6.03 \\ 2 \pi = 2*314=6.28[/tex]
So we have
0.477, 5.22,6.03,6.28
And 6.28 is the largest among them. Therefore correct option is 2pi .
