(B)
Explanation:
4 quarts are in a gallon so one gallon equals 4(1). The one represents the amount of gallons so if there are x gallons it would become 4(x)
        
             
        
        
        
Answer:
The ball holds 113.0 cubic inches of air 
Step-by-step explanation:
Firstly we need to know the shape of the ball
A ball is spherical in shape 
So to know the number of cubic inches, we have to find the volume of air in the ball
Mathematically, we can do this by finding the volume of the ball using the formula for the volume of a sphere 
The formula for the volume of a sphere is ;
V = 4/3 * pi * r^3
in this case, r = d/2 = 6 /2 = 3 inches 
where r is the radius of the ball and d is the diameter of the ball
So, substituting these values , we have 
V = 4/3 * 3.14 * 3^3 = 113.0 cubic inches
