How is the answer 100.48 ?? Someone explain I'm confused

Use the following formula:
[tex]A=2\pi rh+2\pi r^{2}[/tex]
Take the value of [tex]\pi[/tex] as 3.14 and add the values in the formula:
[tex]A=2(3.14)(2)(6)+2(3.14)(2)^{2}[/tex]
[tex]A=75.36+25.12[/tex]
[tex]A=100.48[/tex]
I hope this helped :)
