Finding Diameter Directly from Known Volume
If you need the total width of a sphere whose volume is known, you can either compute the radius and double it, or use the direct diameter inverse equation:
d = ³√[ (6 × V) / π ]
Example Calculation
A spherical meteor has an estimated volume of V = 1,200 cm³. What is its diameter?
- Multiply by 6:
6 × 1200 = 7200 - Divide by π:
7200 / 3.14159265 ≈ 2291.83 - Take cube root:
³√(2291.83) ≈ 13.18 cm
The diameter of the meteor is approximately 13.18 cm.
