Verified Answer :

V=4/3 x pi r cubed thats the ewuation for the volume of a sphere

Here:
If the diameter = 2.28, then in order to find the volume of a sphere, you would have to divide it by 2 in order to find the radius.
SO, the radius would be 1.14.

In order to find the volume of a sphere, you:

\(r^{3} * \pi *4/3 = volume of sphere\)

So, your answer is 6.21.
