Question 1059345: Determine number of lead balls in a lb. if the diameter is 1/4 inch. Lead weighs .41 lbs. / cu. in.
Not homework problem.
Partial attempt:
16 oz. = 1 lb.
Volume of sphere; 4/3 * pi * r^3
1.333 * 3.1416 *.125 * .125 * .125 =.00081 cu. in.
Unsure how to proceed. Thanks.

You can put this solution on YOUR website!
1%2F8 of an inch is the radius of a lead ball, and given density is 0.41%28pounds%2Fcubicinch%29.


How many of these lead balls in ONE POUND?

Find first the volume of 1 lead ball.
%284%2F3%29pi%281%2F8%29%5E3, cubic inches.

-------understand that the pi appears out-of-place and is a FACTOR; not an exponent.

That is completely unsimplified, so what is still needing be done is to simplify it.
