Suppose the area of a circle is 9pi . What is its diameter?

Answers

Answer 1

Answer:
Hi There!

r = 3
So the radius is 3, and the diameter is twice the radius, so multiply by 2.

3 * 2 = 6

So the diameter is 6.

Hope This Helps :)

I think its 2 because if you divide 20,000 over 1000 you get 2. If you do that for the other values, you would also get 2.

What is the equation of the line containing the points (3,1), (9,3) and (27,9)

Answers

Answer:

y = (1/3)x

Step-by-step explanation:

If this is truly a line, then we can find its equation using any two of the three given points. If we go from (3, 1) to (27, 9), x increases by 24 and y increases by 8. Thus, the slope of this line is m = rise / run = 8 / 24, or m = 1/3.

Using the point (3, 1) and the slope m = 1/3, the slope-intercept form y = mx + b becomes 1 = (1/3)(3) + b. Thus, b = 0, and the line is y = (1/3)x.
