Question

What is the volume of a sphere? (use $\pi =3.14$)

• A. $6,878.82{in}^3$
• B. $6,578.82{in}^3$
• C. $5,878.82{in}^3$
• D. $6,808.82{in}^3$

Answer 1

The correct option is A $6,878.82{in}^3$

Formula:

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

where,

$r=radius$

Given:

$r=11.8$

After substituting the values in the formula we

$\frac{4}{3}\pi r^3=\frac{4}{3}\times 3.14\times {11.8}^3$

$=\frac{4}{3}\times 3.14\times 11.8\times 11.8\times 11.8$

$=\frac{20636.481}{3}$

$=6878.82i{n}^3$
