Answer:
C. 
Step-by-step explanation:
The volume of the ball with radius R can be calculated using formula

A basketball has a diameter of 9.5 cm, so its radius is

Hence, the volume of air the basketball can hold is

Answer:
x = -2
Step-by-step explanation:
From x = -2 to x = 5, f' is negative. That means f is decreasing.
From x = 5 to x = 6, f' is positive. That means f is increasing.
The negative area (between x = -2 and x = 5) is larger than the positive area area (between x = 5 and x = 6). That means f decreases more than it increases.
So f is an absolute maximum at x = -2.
1/4, since the radius is also halved if the diameter is halved, meaning (radius/2)^2 is radius^2 * 1/4.
D because they are 9 ponits between them so the abs are going going to remove the negative
