.
a lawn roller is a cylinder 0.96m long and 0.6m in diameter.
How many revolutions of the roller are needed to roll 76m^2 of lawn?
thanks for answering.
~~~~~~~~~~~~~~~~~~~~~~~~~~
The area equation for this problem is
76 = 0.96*(pi*0.6)*n square meters,
where n is the number of revolutions, 
= 3.14 (approximately).
From this equation
n = 
= 42.02052.
Probably, you want (or, may be, do not want) to round it to 42 revolutions.
Solved.
