The volume of two spheres is shown:
Sphere A = 30 cubic inches
Sphere B = 10 cubic inches
How many inches more is the radius of sphere A than the radius of sphere B? Round your answer to the nearest tenths. (Use π = 3.14.) (1 point)
Group of answer choices

0.6 inch

1.3 inches

1.9 inches

20.0 inches

≈ 1.3 inches

Step-by-step explanation:

Given that:

As we know, the formula to find the volume of a sphere is;

V = π

So we have:

<=> π  = 30

<=>  = 90/4π

<=> r ≈ 4.13

<=> π  = 10

<=> = 30/4π  

<=>  r ≈ 2.86

So the  different between the radius of sphere A and B is:

= 4.13 - 2.86

= 1.27

≈ 1.3 inches
