Question 1058811: Ref. Question 1058808 Follow-up:
Determine number of glass marbles produced from 15 lbs. of material, allowing 5% for waste. The marbles are 1.5 in. in diameter.
Volume of sphere = 4/3 * pi * r^3.
1.333 * 3.1416 * .625 * .625 * .625 = 1.022 cu. in.
Not sure from this point.
Additional info; Glass weighs .0945 lbs. / cu. in. My apology for the omission.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The 95% remaining amount of the glass (after taking off 5% for waste) is
0.95*15 = 14.25 lbs.
It corresponds to the volume of glass = 150.79 cu. in.
The number of spherical glass marbles is = 150.46 ---> (round) ---> 150.
Answer. 150 spherical glass marbles.
