<pre>
The area equation for this problem is

    76 = 0.96*(pi*0.6)*n  square meters,


where n is the number of revolutions, {{{pi}}} = 3.14 (approximately).


From this equation

    n = {{{76/(0.96*3.14*0.6)}}} = 42.02052.


Probably, you want (or, may be, do not want) to round it to 42 revolutions.
