Answer:
15.7
Step-by-step explanation:
Assuming they are circular, just to clarify.
First cutter:
A=pi*r^2
r=d/2
d=4
r=2
pi*2^2
3.14*4
Second cutter:
r=3
pi*3^2
3.14*9
Differences:
3.14*9-3.14*4
3.14*(9-4)
3.14*5
15.7
Notes: I used 3.14 as pi as it does not need to be any longer for rounding to the tenths place. To sum it up, I found the areas of each cutter, assuming that they are circles, then calculated the difference.
So remember that the area of a triangle is
. Using this info, we can make the equation 
All you need to do is multiply everything, and your answer will be 
In short, the area is 7/12 yds^2
