So First of all we need to know how to find the area of a circle.
Assuming that the apple pie is the shape of a circle
The formula for area is [tex] \pi [/tex] [tex] r^{2} [/tex]
Well we know that the radius = 3.14
And we know that [tex] \pi [/tex] = 3.14 as well.
All we have to do is multiply..
3.14 x [tex] 3.14^{2} [/tex] = 30.95
So the area of the pie is 30.95 in
Good Luck! :)
