(x-h)^2+(y-k)^2=r^2
r=radius
(x-3)^2+(y+4)^2=14
(x-3)^2+(y+4)^2=(√14)^2
answer is 2nd option
r=√14
Y=2x+0. The two would be next to the x, because that represents the slope. And it would plus zero, because zero is the initial value, since it's passing through the origin.
Answer:
x = 20
Step-by-step explanation:
The three angles form a straight line so they add to 180 degrees
x+ 100 +3x = 180
Combine like terms
100+4x= 180
Subtract 100 from each side
100+4x-100= 180-100
4x= 80
Divide each side by 4
4x/4 = 80/4
x = 20
Answer:
r=6
Step-by-step explanation:
The area of a circle is given by πr². Note that this uses the radius, not the diameter.
Now, one quarter of this area (ABC) is given to be 9π.
So apparently:
If you solve this:
(divide both sides by π)
(multiply both sides by 4)
so
r = √36 = 6
so the radius is 6.
