Answer 1

Answer:

$3589.5\ m^3$

Step-by-step explanation:

Given,

Diameter of the sphere = 19 m

We have to find out the volume of the sphere.

Solution,

Firstly we will find the radius of the sphere.

Radius is equal to half of the diameter.

$radius = \frac{19}{2}=9.5\ m$

Now using the formula of volume of sphere.

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

where 'r' is the radius.

Now substituting the values, we get;

Volume of sphere = $\frac{4}{3}\times3.14\times9.563=3589.5\ m^3$

Hence the volume of sphere is $3589.5\ m^3$.
