Question

What is the volume of a sphere with a radius of 3 m, rounded to the nearest tenth

Answer 1

Given:-

$\rightarrow$Radius(r) of sphere = 3m

To Find:-

$\rightarrow$ Volume of the sphere.

Formula Used:-

$\rightarrow$Volume of sphere = $\sf{\frac{4}{3}πr^3}$

Solution:-

$\rightarrow$Volume of sphere = $\sf{\frac{4}{3}πr^3}$(putting the value of r(radius) from the above given and pie(π) = $\sf{\frac{22}{7}}$)

$\rightarrow$$\sf{=\frac{4}{3}×\frac{22}{7}×3^3}$

$\rightarrow$$\sf{=\frac{4}{3}×\frac{22}{7}×27}$

$\rightarrow$$\sf{=\frac{2,376}{21}}$

$\rightarrow$$\sf{=113.14m^3}$

Therefore, the volume of the sphere $\sf{=113.14m^3}$, which can be rounded off to it's nearest tenth as $\sf{113.1m^3}$
