Answer:

Step-by-step explanation:
The formula of a volume of a sphere:

R - radius
We have R = 3 ?. Substitute

If the radius is 30, then the volume is:

If 30 is the length of diameter, then the radius R = 30 : 2 = 15.
Therefore the volume:

Seven pizzas: 7 pizzas
Shared between 3 friends: 7 pizzas / 3 friends
Simplify the fraction:
7 / 3
(3 goes into 7 twice, 7 - 6 = 1)
2 1/3
The fraction of pizza that each friend gets is 2 1/3.
Hope this helps!! :)
