Step-by-step explanation:
Equation of a line:
The equation of a line, in point-slope form, has the following format:

In which the point is
and the slope is m.
(3, 20)
This means that
. So


Slope:
The slope is the derivative of the function at the point:
The function is:

The derivative is:

At the point, we have that
. So

So the equation to the tangent line to the curve a the point is:

Answer:
Step-by-step explanation:
you do 10/2 for the radius, so that will be 5. then you do 3.14*5*5= 78.5
Answer:
