No that is incorrect because the circumference for the circle is 3.14
Answer:
≈ 1.3 inches
Step-by-step explanation:
Given that:
- Sphere A = 30 cubic inches
- Sphere B = 10 cubic inches
As we know, the formula to find the volume of a sphere is;
V = π
So we have:
- Sphere A = 30 cubic inches
<=> π = 30
<=> = 90/4π
<=> r ≈ 4.13
- Sphere B = 10 cubic inches
<=> 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
