Problema Solution
How many ball bearings, each with a diameter of 1 cm, can be made using 5.24 cm3 of molten steel?
Answer provided by our tutors
The volume of the ball is V = (4/3)(1/2)^3 pi
Let x represent the number of balls:
V*x = 5.24
(4/3)(1/2)^3 pi * x = 5.24
pi = 3.14
(4/3)(1/2)^3 * 3.14 * x = 5.24
........
........
x = 10 balls
10 balls can be made.
