Please help me with this circle area problem for geometry

Answer:
circle area = PI * radius^2
circle area = 11^2 * PI
circle area = 121 * PI
That would be the area for the ENTIRE area but the circle but we are only dealing with 135 degrees of a circle so the area equals
121 * (135 / 360) * PI
= 45.375 PI
