What is the volume of this sphere?

Natasha_Volkova [10]

Answer:

Option c. 11,488.21 cm3

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The volume of the sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$r=28/2=14\ cm$ ---> the radius is half the diameter

$\pi =3.14$

substitute

$V=\frac{4}{3}(3.14)(14)^{3}$

$V=11,488.21\ cm^3$
