12 sq in
576 sq in

Answer 1

blake, look up the formula for how to find the area of a circle

Answer 2

Use the formula A = to find the area

Answer 3

THe area formula of a circle is \[\Pi r ^{2}\] You know the radius, so all you have to do is plug in the correct numbers into the equation.
\(\pi\) = 3.14
r=12
So now your equation will look like this
...

Answer 4

\[3.14\times12^{2}\]

Answer 5

OR...

Answer 6

\[3.14\times12\times12\]After you finish that math, what do you get?
