Answer:
The volume increases at a rate of
Step-by-step explanation:
The rate of change of the radius with respect to time is 4 mm / s.
So:
Now we must find a relationship between the volume of a sphere and its radius.
The equation of the volume of a sphere is:
So:
The diameter of the sphere is 100 mm. Therefore its radius is 100/2 = 50 mm.
So:
The volume increases at a rate of :
40000 π mm ^ 3 / s = 125663.71 mm^3/s
<h3>Hm ok, so the correct answer here would be (0,3) and heres why:</h3>
If the y would be equal to 0, everything would then just depend if you add or subtract the x:
Now the first answer could be correct for:
However, this answer is not correct for the other equation. the same true for all the other answers except (0,3)
