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.)

Answer:
The rate of change is $15/day
Step-by-step explanation:
The rate of change, using the points (1,60) and (5,120)
m= (y2-y1) / (x2-x1)
= (120-60)/ (5-1)
= 60/4
= 15
The rate of change is $15/day
20/2=10 because the formula for acceleration is velocity or speed (20) divided by time (2)
