Answer:
The rate of change of the area of the circle is approximately .
Step-by-step explanation:
Given:
radius
We need to find the rate of change of the area of the circle at that instant.
Solution:
Now we know that;
Area of the circle is given by π times square of the radius.
framing in equation form we get;
to find the rate of change of the area of the circle at that instant we need to take the derivative on both side.
Substituting the given values we get;
Hence The rate of change of the area of the circle is approximately .
0.25
The linear equation/slope intercept form is y=mx+b
M is the slope and b is the y-intercept.
So the equation would be: y=2x+4
