Answer:
x² + (y + 8)² = 49
Step-by-step explanation:
You didn't ask a question
Did you want the equation for the circle?
--------------------------
Standard form is
(x - h)² + (y - k)² = r²
using (h, k) = (0, -8)
x² + (y + 8)² = r²
use the area to find r²
a = πr²
49π = πr²
Divide both sides by π
49 = r²
Now the equation can be completed
x² + (y + 8)² = 49
