Answer:
Step-by-step explanation:
First let's find the circle without the gray area. We would have:
[tex]\pi r^2=\pi 36^2=\pi1296[/tex]
Next let's find the area of the circle with the gray area. We would have:
[tex]\pi r^2=\pi50^2=\pi2500[/tex]
Now we subtract and get:
[tex](2500-1296)\pi=\boxed{1204\pi}[/tex]
