Answer:
-16
Step-by-step explanation:
(-3 + (-5))(-3 - (-5))
(-3 - 5)(-3 + 5)
(-8)*2
<u>-16</u>
I believe it would be (b) (-2,1)
If the diameter is 16, then the radius is 8.
A=(pi) r^2
8*8=64
64*3.14159265359=201.06
201.06 is your answer.

Given:
The given equation is:

A line is perpendicular to the given line and passes through the point (4,-1).
To find:
The equation of required line.
Solution:
The slope intercept form of a line is:

Where, m is slope and b is y-intercept.
We have,

Here, the slope of the line is -4 and the y-intercept is 3.
Let the slope of required line be m.
We know that the product of slopes of two perpendicular lines is -1. So,



The slope of required line is
and it passes through the point (4,-1). So, the equation of the line is:




Therefore, the equation of the required line is
.
