It is the third one that is the answer
Let's assume the redius of the given circle is (r).
so,
- circumference =
- Area =
<u>According</u><u> </u><u>to</u><u> </u><u>the question</u><u>, </u>
<em>circumference of a circle is 2/3 of its area.</em>
<u>Therefore</u><u>, </u><u>the length of the radius of the circle</u><u> </u><u>is</u><u> </u><em>3</em><em> </em><em>unit</em>
Answer:
3y= -2x-6
Step-by-step explanation:
The two points on the line are (-3,0) and (0,-2)
so you first get the gradient;
gradient= <u>change in y</u>
change in x
= <u>-2-0</u>
0-(-3)
=<u> -2</u>
3
so the answer above is the gradient
then pick one point that you used to get the gradient with, so as for me I'll pick (-3,0) and then a general point which is always (x, y)
since you have the gradient you can easily get the equation by doing this
<u>y-0</u><u>. </u><u> </u> = <u>-2</u>
x-(-3). 3
then crossmultiply to get the equation of the line
3y= -2(x+3)
3y= -2x-6
9.8 is a rational number that is between 9.7 and 9.9. Hope this helps!
