Answer:
Beach ball with diameter of 24 inches what is the volume of air in the beach ball to the nearest of a cubic foot?
1 answer:
Answer:
4 ft³
Step-by-step explanation:
From the question;
- Diameter of the beach ball is 24 Inches
We are required to determine the volume of the air in the beach ball;
- We need to know that the volume of the air is the same as the volume of the beach ball.
- The ball is in the shape of a sphere
Radius = 12 inches
But, 1 ft = 12 inches
Thus, radius = 1 ft
Therefore;
Taking pi as 3.142
Volume = 4/3 × 3.142 × 1³
= 4.189 ft³
= 4 ft³ (nearest cubic foot)
Therefore, the volume of the air in the beach ball is 4 ft³

Answer:
C) domain: all real numbers greater than or equal to 0
range: all real numbers greater than or equal to 13,000
Step-by-step explanation:
We have, the function for the cost of laying cable is given by,
, where x is the length of the cable (in feet).
As, 'x' represents the length of the cable.
We have that, the value of x cannot be negative.
So, x ≥ 0.
Since, the domain of is the set of points where
and we have that x ≥ 0.
Thus, the domain is 'Set of all real numbers greater than or equal to 0'.
Now, we substitute x= 0 in .
i.e.
i.e.
i.e.
i.e. c(0) = 13000.
So, we get that the vertex point of the function is (0,13000).
Thus, the range is 'All real numbers greater than or equal to 13,000'.
