$\blue\textsf{\textbf{\underline{\underline{Question:-}}}}$

What is the volume of a sphere if its radius is 3 m?

$\Large\boxed{\:\:\:\:\:\:\:}$ cubic meters

$\blue{\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}$

$\textsf{Volume\:of\:a\:sphere:-}$

$\bigstar$$\boxed{\bold{V=\displaystyle\frac{4}{3} \pi r^3}}$

Where

$\bold{V\:=\:volume}$

$\bold{\pi \:=\:pi\:(3.14...)}$

$\bold{r\:=\:radius}$

Given:-

$\bold{r=3m}$

Solving for Volume:-

$\bold{V=\displaystyle\frac{4}{3} \pi (3)^3}$

Cube the radius:-

$\bold{V=\displaystyle\frac{4}{3} \pi *27}$

Multiply:-

$\bold{V=113.04m^3}$ (rounded to the nearest hundredth)

So the volume of this sphere is

$\boxed{\bold{113.04\:\:\:\:\:\:\:\:\:}}$ cubic meters

Good luck.

Answer 2

Answer:

113.04 ≈ 113 m³

Step-by-step explanation:

Given that,

→ Radius (r) = 3 m

Formula we use,

→ 4/3 πr³

Let's solve the problem,

→ 4/3 πr³

→ 4/3 × 3.14 × 3 × 3 × 3

→ 4/3 × 3.14 × 27

→ 4/3 × 84.78

→ 339.12/3

→ 113.04

→ [ ≈ 113 m³ ]

Hence, volume of sphere is 113 m³.
