Answer:

Step-by-step explanation:
The formula of an area of a circle:

<em>r</em> - radius
We have the endpoints of a diameter of a circle.
The formula of a distance between two points:

Substitute the coordinates of the given points A(3, 4) and B(10, 4):

Therefore we have the length of the diameter: <em>d = 7</em>
We know: <em>d = 2r.</em> Therefore

Substitute to the formula of an area:

<em>There is no such answer in the answers to choose.</em>
<em>Apparently you have some error in the coordinates of the endpoints.</em>
Answer:
Yes, this is linear.
y = -4x
Step-by-step explanation:
12x = 7y - 10y
12x = -3y
-3y = 12x
/ -3 /-3
y = -4x + 0
