Answer:
If we say the circumference is 1600 pi, and this is equal to pi times the diameter, we can just divide both sides by pi to get the diameter, which is going to be 1600.
Step-by-step explanation:
Answer:
ZX
Step-by-step explanation:
A diameter is a chord of a circle that passes through the center of the circle.
A chord of a circle is a segment inside the circle whose endpoints are on the circle.
Chords of the circle:
ZY, ZX, YW, UV
Of all those chords, only two pass through the center of the circle:
ZX, YW
Of the two diameters, only one is a choice:
ZX
Answer: B. ZX
Consider ΔAQD. This triangle has the area
where H is the heigh drawn from the point Q to the side AD.
Note that the height H is also the height of the parallelogram. So the area of the parallelogram ABCD is
From these two statements you can conclude that
Now consider ΔDMQ. The ratio between the area of triangles DMQ and AQD is
Since you have that
and
Thus,
Answer: correct choice is B
Answer:
The slope is (1, 3)
Step-by-step explanation:
You would subtract the two plots. It looks like they are (3,5) and (2, 2). So take the two ys and subtract them over the two xs. 5-2 is 3 and 3-2 is 1. You would get a slope of 3/1 or (1, 3) This means that on the graph your point has traveled up 3 and right by 1. Hope this helps! :)
