Answer:
<em>Answer: d) -310pi</em>
Step-by-step explanation:
<u>Instantaneous Rate of Change</u>
Is the change in the rate of change of a function at a particular instant. It's the same as the derivative value at a specific point.
The surface area of a cylinder of radius r and height h is:

We need to calculate the rate of change of the surface area of the cylinder at a specific moment where:
The radius is r=8 mm
The height is h=3 mm
The radius changes at r'=-9 mm/hr
The height changes at h'=+2 mm/hr
Find the derivative of A with respect to time:


Substituting the values:

Calculating:




Answer: d) -310pi
4x+4+8=24
4x+12=24
-12. -12
4x =12
divide by 4
x=3
I think your answer would be B
Answer:
Unit fraction
