The volume of sphere is 4851 cm cube then its diametrer is

Answer»

The diameter of SPHERE is 21 cm.  

Given:

The volume of sphere = 4851 cm ^{ 3 }

To FIND: Diameter of sphere = ?

Solution:

The sphere is a “three dimensional” OBJECT which is perfectly round in shape of ball LIKE structure.  

Volume of sphere = \frac{4}{3} \pi r^{3}

\begin{array}{l}{\frac{4}{3} \pi r^{3}=4851} \\ \\{r^{3}=\frac{4851 \times 3}{4 \times \pi}} \\ \\{r^{3}=\frac{14553}{12.564}} \\ \\{r^{3}=1158.309} \\ \\{r=\sqrt[3]{1158.309}}\end{array}

r = 10.5  

Diameter of the sphere = 2 \times radius =2 \times 10.5

D = 21 cm
