The question, as stated, cannot be answered sensibly. An acre is a measure of area, with dimensions [L2]. A mile is a measure of distance, with dimensions [L]. The two measure different things and elementary dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
352 acres = 0.55 square miles
352 km = 218.722 mi.
There are no miles in any acres, and no acres in any miles.1 square mile = 640 acres
90 acres=0.141 square miles and I am sorry, but I do not know how many miles not squared are in 90 acres.
0.2 miles = 352 yards.
1,024,000 acres.
There is 0.234375 miles in 150 acres
2,560 Acres.
42,000 Acres = 65.625 Square Miles
There are 5280 feet in one mile. Therefore, 352 feet is equal to 352/5280 = 0.06 recurring (that is, 0.06666...) miles.
Acres are area. Miles are length.
0.45625 square miles in 292 acres.
