Answer 2

As per data given in the question,

We have to determine the value of the sphere.

From the question,

We have,

Length of diameter = 3 cm

So, radius of the sphere will be $\frac{3}{2} = 1.5\: cm$

As we know that,

Volume of sphere will be $=\frac{4}{3}\Pi r^3$

So, putting the value of radius in the above equation,

We will get,

$=\frac{4}{3}\Pi r^3\\=\frac{4}{3}\times3.14\times 1.5^3\\=\frac{4}{3}\times3.14\times 1.5\times 1.5\times 1.5\\=14.13\:cm^3$
