Answer:

0.6 in

Step-by-step explanation:

  • Volume of the sphere formula: V = 4/3πr³, where r is the radius

Given:

  • Volume of Sphere A = 30 cubic inches
  • Volume of Sphere B = 10 cubic inches

Let R be the radius of sphere A and r be the radius of sphere B

  • 30 = 4/3*3.14R³
  • R³ = 30*3/(4*3.14) ≈ 7.2
  • R = ∛7.2 ≈ 1.9 in

And, similarly,

  • r³ = 10*3/(4*3.14) ≈ 2.4
  • r = ∛2.4 ≈ 1.3 in

The difference:

  • R - r = 1.9 - 1.3 = 0.6 in
