Circumference of a circle = pi%2Ad
each revolution advances the roller pi%2Ad 0r .6%2Api
72m%2F%28.6m%2Api%29 is the number of revolutions needed to roll 76m of lawn
IF You meant 76m^2 of lawn
THEN: n = 72m%2F%28.96%29%28.6m%2Api%29
(The denominator representing a rectangular area for each revolution:
+%28.6m%2Api%29x .96m )
