Question 1051166: A man, having no measuring device, measured the length and width of a field by counting the revolutions made by a wheel. He discovered the measurements to be 60 and 22 revolutions, respectively. The wheel is 3 ft. 4 in. in diameter. Determine number of acres in the field.

Circumference = pi * diameter.
3.1416 * 3.33 = 10.46 ft.
Acre = 43,560 sq. ft.

Using what you presented,
+60%2A10.46+=+627.6+
+22%2A10.46+=+230.12+
+627.6%2A230.12+=+144423.312+
This is the area of the field in square feet
---------------------------------------
[ sq ft ] x [ acres/ sq ft ] = [ acres ]
+144423.312%2A%28+1%2F43560+%29+=+3.3155+ acres
----------------
