Answer:
254.4 in²
Step-by-step explanation:
Area of a circle is given by the formula:

Our radius is 9 so we substitute this into the equation:
π(9)² = 81π
81π = 254.4 in²
Answer:
The answer is
<h2>y = - 8x + 8</h2>
Step-by-step explanation:
To find the equation of the line given a point and slope we use the formula

where
m is the slope
( x1 , y1) is the point
From the question the point is
(1/2,4) and slope m = -8
The equation of the line is

We have the final answer as
<h3>y = - 8x + 8</h3>

Yes you can. If a vertical line passes trough a line more than once in a graph, then it is inverse but if it passes trough only once it is a function
