Question

Calculate the volume of a sphere whose radius is $12$ m.

• A. $7134.56m^3$
• B. $7234.56m^3$
• C. $7034.56m^3$
• D. $7334.56m^3$

Answer 1

The correct option is B $7234.56m^3$

Formula:

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

$r=radius$

Given:

$r=12m$

$\Rightarrow \frac{4}{3}\pi r^3=\frac{4}{3}\ast 3.14\ast {12}^3$

$=\frac{4}{3}\ast 12\ast 12\ast 12\ast 3.14$

$=\frac{4}{3}\ast 1728\ast 3.14$

$=\frac{21703.68}{3}$

$=7234.56m^3$
