If the volume of a sphere is 792/7 cc. The radius of the sphere will be1. 9 cm2. 3 cm3. 6 cm4. 9/7 cm |

Answer» Correct Answer - Option 2 : 3 cm Concept: Let the radius of a sphere is R meters, The volume of the sphere = \(V=\frac{4}{3}{\rm{\pi }}{{\rm{R}}^3}\) Surface area of the sphere = S = 4πr2 Calculation: Given that V = 792/7 cc \(\frac{792}{7}=4\times\frac{22}{7}\times\frac{R^3}{3}\) R3 = 27 R = 3 cm |
