The equation for the area of a circle is $$\pi r^2$$Can you figure this out?

anonymous · Answer

well not really lol its kind of hard for me @mossyfish

anonymous · Answer

I get confused between two steps that's why

anonymous · Answer

That's okay!

You multiply pi by the radius squared.

So, let's find out what the radius is.  4, right?  What is 4 squared??

anonymous · Answer

4x4?
I think if not I am getting it confused with some other math

Yup!  4*4 is 4^2.  Exponents (^number) means that you multiply the number (in this case 4) by itself however many times the exponent is.  

So, 4*4=?
