Question

A manufacturer makes ball bearings out of molten steel. It takes 5.24 cubic centimeters of molten steel to make ___ ball bearings that each have a diameter of 1 centimeter.

Answer 1

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.
