We know that the area of a circle is represented by the equation:
And we know that the diameter of a circle is twice the radius:
So if we know that the diameter is 13m, we can solve for the radius:
-->
Then we can plug in this radius into the equation for the area of a circle, using 3.14 to approximate the value of pi:
So now we know that the area of the circle is 132.665 square meters.
The slope of the line is 6, meaning that you can eliminate A,C. Since the point slope formula is y-y1=m(x-x1) you just need to see if the points are correct.
B. (3,9)
D. (1,-3)
While these do contain one point, substitute the coordinates to see which contain both.
B.
(1,-3): -3-9=6(1-3): -12=-12
(3,9): 9-9=6(9-3): 0= 6(6)
D.
(1,-3): -3+3=6(1-1): 0=6(0); 0=0
(3,9): 9+3=6(3-1): 12=6(2): 12=12
D is correct since the coordinate are on the line.
