    Answer:

      R=0.39789 ft

    Step-by-step explanation:

    For the perfectly mowed lawn, after one revolution, you want the lawnmower to be exactly one lawnmower’s width closer to the pole. This implies that one lawnmower width should wrap around the circumference of the pole every revolution. So for this lawnmower we want:

    2πR=2.5

    ⇒R=2.5/2π

      R=0.39789 ft
