The formula for surface area of a sphere is A=4*PI*r^2
Using that formula and the known surface are we can find the radius. We can then use that to find the volume.
500 = 4*PI*r^2
Divide both sides by 4:
500/4 = PI *r^2
125 = PI *r^2
Divide both sides by PI
125/PI = r^2
39.79 = r^2
r = SQRT(39.79)
r = 6.3 cm
Now we can find volume using V=4/3*PI*r^3
V = 4/3 *PI *6.3^3
V= 1051.3
The answer is C
This is obvious come on Joe is correct

Using a linear function, the graph for the amount remaining of the trip is given at the end of this answer.
------------------------------
The linear function that models the distance remaining is given by:

In which
- D(0) is the total distance.
- v is the velocity.
In this problem:
- 500 miles, thus

- 55 miles per hour, thus:

The time it takes is:

Thus, the function is:

The graph is given at the end of this answer.

Answer:
6
Step-by-step explanation:
3k + 5 = 23
3k = 23 - 5
= 18
k = 18/3
= 6
