Answer:
B, D, and E
Explanation:
First, the formula for the area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]
Since pi is equal to 3.14, all we need is the radius squared. Since your radius is 12, [tex]12^{2}[/tex]=144. Therefore, your equation for area will be (3.14)(144), answer B.
Second, the formula for the circumference of a circle is [tex]2\pi r[/tex].
So, 2(3.14)(12), answer D.
Edit: Answer E also says the same as above- it just multiples the 2 and the 12 together. Sorry for the initial error!
