Question 1059604: Non-homework.
A coil of steel wire weighs 50 lbs., diameter 0.025 in. Steel weighs .283 lbs. / cu. in. Determine length of wire.
The wire is a regular cylinder.
Area of circle; pi * r^2.
3.1416 * 0.0125 * 0.0125 = 0.0049 sq. in.
0.0049 * 1 = 0.0049 cu. in. (volume of 1 ft.)
50 / .283 = 176.678 = 177 cu. in. (vol. of wire).
177 / 0.0049 = 36122.48 ft.

Question 1059712: Ref. Question 1059604:
A coil of steel wire weighs 50 lbs., diameter 0.025 in. Steel weighs .283 lbs. / cu. in. Determine length of wire.
The wire is a regular cylinder.
Area of circle; pi * r^2.
3.1416 * 0.0125 * 0.0125 = 0.0049 sq. in.
0.0049 * 1 = 0.0049 cu. in. (volume of 1 ft.)
50 / .283 = 176.678 = 177 cu. in. (vol. of wire).
177 / 0.0049 = 36122.48 ft.
Corrected:
3.1416 * 0.0125 * 0.0125 = 0.00049 sq. in.
0.00049 * 12 = 0.00588 (vol. of 1 ft.)
50 / .283 = 176.678 = 177 cu. in. (wire vol.)
177 / 0.00588 = 30102.04 ft.
