=144. Therefore, your equation for <em>area</em> will be (3.14)(144), answer B.
Second, the formula for the circumference of a circle is
.
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!
The origin would be Meteorology> :)
