Answer:

263.08 m²

Step-by-step explanation:

The fraction of circle area that a sector represents is proportional to the central angle.

<h3>Proportion</h3>

circle area/circle angle = sector area/sector angle

circle area / 360° = 85.5 m² / 117°

Multiplying by 360°, we have ...

circle area = (360/117)(85.5 m²) = 263.08 m²

The area of the circle is about 263.08 m².
