Answer:
681.47 π cubic inches
Step-by-step explanation:
Given : A properly inflated basketball measures 8.8 inches across.
To Find: What is the total volume of air inside six of Jake’s basketballs?
Solution:
Diameter of ball = 8.8 inches
Radius = Diameter/2 = 8.8/2 = 4.4
Since we need to calculate the volume of air inside the ball which is in the shape of sphere
So, formula we will use
Volume of sphere =
Where r is radius and use π =3.14
Thus the volume of air inside the ball =
=
=
since there are 6 balls
So, Volume of air in 6 balls =
=
Hence the volume of air in six balls 681.47 π cubic inches

Given:
Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster.
To find:
The graph that represents the set of heights that satisfy this requirement.
Solution:
Let x be the height required for the ride.
Guests must be at least 54 inches tall to be able to ride the roller coaster. It means required height is greater than or equal to 54.
So, 54 and all values above 54 are in the solution set.
Since, 54 is included in the solution set, therefore there is a closed circle at 54. All values above 54 are in the solution set, so everything to the right of the circle is shaded.
Therefore, the correct option is C.
