Answer:
Step-by-step explanation:
Area of a circle is equal to
, where r is the radius
![A=\pi r^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2)
A diameter is twice the length of the radius. (
)
So the radius is 4 cm.
![r^2=4^2=16](https://tex.z-dn.net/?f=r%5E2%3D4%5E2%3D16)
so the Area is ![16\pi](https://tex.z-dn.net/?f=16%5Cpi)
Answer:
-4/5x-3
Step-by-step explanation:
We can eliminate the options C and D as they have a +3 which means they would start at (0,3).
y=-4/5x-3
y=-4/5(-5)-3
y=4-3
y=1
same thing from last question
1=-4/5x-3
+3 to both sides
4=-4/5x
*5/4 to get 1x
5=-x
*-1 to get positive x
-5=x
which proves my answer as correct
