Find area
area=pir^2
d/2=r=50/2=25
A=pi25^2
a=pi625
aprox pi=3.141592
a=1963.495
that is how many square feet
multiply that by 120
1963.495 times 120=$235,619.4
Answer:
(Missing part of the question is attached)

Estimates are too large.
Step-by-step explanation:
Suppose the only information we know about the function is:

where the graph of its derivative is shown in the attachment
<h3>(a)</h3>
If the function
is differentiable at point
, the tangent line to the graph of
at 1 is given by the equation:

So we call the linear function:

We know the
as it is given in the question, and
from the graph attached. Substitute in the equation of
.

<h3>(b)</h3>
At x=1,
is positive but it is decreasing. However. if we draw the tangent lines, we see that the tangent lines are becoming less steeper, so the tangent lines lie above the curve
. Thus, The estimates are too large.
Answer:
D) 15
Step-by-step explanation:
The sum of the interior angles of a polygon is given by

We have that, the sum of the interior angles of a polygon is
26 right angles. We want to find n, the number of sides.
We substitute into the formula to get:

Divide through by 90

Divide through by 2



B. D=0.25n + 25
D=total n=number of hours 0.25=price per hour 25=the one time fee
