DEV Question #3

Serena is standing at the center of a room measuring 11m x 20m. She can spin in a circle covering an area of 201.06m^2. Her wand gives her an attack radius of 1m. The area of her total attack range is calculated to be 197.92m^2 by subtracting the area of her wand radius (3.14m^2) from the total area covered by her spin (201.06m^2).
