This function is in vertex form: f(x)=a(x-h)^2 - k
Where (h , k) is the vertex. x=h is the axis of symmetry.
Vertex (1,-5) axis of symmetry x = 1

Answer:
A = 121π in²
Step-by-step explanation:
The circumference (C) of a circle is
C = 2πr ( r is the radius )
Here C = 22π , that is
2πr = 22π ( divide both sides by 2π )
r = = 11
The area (A) of a circle is
A = πr² = π × 11² = 121π in²
