How many ball bearings, each with a diameter of 1 cm, can be made using 5.24 cm3 of molten steel? A) 4. B) 7. C) 8. D) 10

First, solve for the volume of the ball bearings by the equation,

V = πd³ / 6

Substituting the value of diameter given,

V = π (1 cm) ³ / 6 = π/6 cm³ = 0.5236 cm³

Divide the amount of material given by this volume,

n = 5.24 cm³ / 0.5236 cm³ = 10

Therefore, there are 10 ball bearings that may be formed.
