Question

What is the volume of a sphere given: (Use $\pi =3.14$)

• A. $1,13,140m^3$
• B. $1,13,040m^3$
• C. $1,03,040m^3$
• D. $2,13,040m^3$

Answer 1

The correct option is B $1,13,040m^3$

Using formula for volume of sphere =$\frac{4}{3}\pi r^3$

$r=radius$

Given: $radius\left(r\right)=30m$

$\Rightarrow \frac{4}{3}\pi r^3=\frac{4}{3}\times 3.14\times {30}^3$

$=\frac{4}{3}\times 30\times 30\times 30\times 3.14$

$=\frac{4}{3}\times 27000\times 3.14$

$=\frac{339120}{3}$

$=113040m^3$
