Answer:
A = \pi r^2
Step-by-step explanation:
to make this simpler i can solve this for you.
To insert the number into the equation you go like this,
A=(pi)r^2
The diameter is that whole line in the circle which is 16 and the r or radius is half the diameter so you would do 16/2, which equals 8. then you insert that into the equation.
A=(pi)8^2
8 to the 2nd power is 64
And im going to round pi to 3.14
so no the equation is
A=3.14*64
The area is 200.96 mi ^2 or rounded 201 mi^2
