So you you are trying to find the area of sphere so you would use this formula
A=4•3.14•r^2
And you already know that the radius is 6 so you would go ahead and plug in the numbers
A=4•3.14•4^2
4^2 is 16 so your final equation would be
A=4•3.14•16
And your answer is
=452.39
8.1 I think but there's an app called, tiger something and it tells,you the answers
There's a site called m.a.t.h.w.a.y, and you can type in those functions in order to get the graph ;)
