Answer:
Radius: 7.75; Volume: 142 (rounded to 3 s.f.)
Step-by-step explanation:
The vollyball is a sphere.
The diameter of a sphere is twice as much as its radius.
Radius = 15.5 ÷ 2
= 7.75
The volume of a sphere is 
r² where r is the radius.
Volume = (7.75)²
= 45.046875
= 142 (rounded to 3 s.f.)
In geometry, an undefined term is a basic figure that cannot be defined in terms of other figures.
The undefined terms in geometry are: point, line and plane.
Since you have not attached any figures, I cannot tell you which one is correct. Just choose the figure that is either a point, a line or a plane.
Answer:
please be more specific
