Answer:
The volume is increasing at a rate of 33929.3 cubic millimeters per second.
Step-by-step explanation:
Volume of a sphere:
The volume of a sphere of radius r is given by:
In this question:
We have to derivate V and r implicitly in function of time, so:
The radius of a sphere is increasing at a rate of 3 mm/s.
This means that
How fast is the volume increasing when the diameter is 60 mm?
Radius is half the diameter, so . We have to find
. So
The volume is increasing at a rate of 33929.3 cubic millimeters per second.
Answer:
And replacing we got:
And the best anwer is
10.12
Step-by-step explanation:
We have the following data given:
62 63 68 72 79 80 83 93 94 95
And we need to begin finding the mean with the following formula:
And replacing we got:
Now we can find the mean absolute deviation like this:
And finally we can find the mean abslute deviation with the following formula:
And replacing we got:
And the best anwer is
10.12
