Area of circle= pi times radius^2
diameter=2 times radius
radius=diameter/2
diameter=12
radius=12/2
radius=6
pi times r&+^2
pi times 6^2
pi times 36
aprox pi=3.14
113.04 in^2
Answer:
So a point is (-3,-5) and the vertex is (-4,-3)
Step-by-step explanation:
This is in vertex form. Vertex form is y=a(x-h)^2+k where (h,k) is the vertex.
The vertex here is (-4,-3)... now just use a value of x to plug in (any value besides -4)
I will choice -3. This gives -2(-3+4)^2-3
f(-3)=-2(1)^2-3
f(-3)=-2-3
f(-3)=-5
So a point is (-3,-5) and the vertex is (-4,-3)
Answer:
Five hundred point two
Step-by-step explanation:
500.2
That's a deimal.
The digit 5 is an hundred. Hence, we have
Five hundred point two
Answer:
x>17/9
Step-by-step explanation:
-3(x-2) < 1/3
-3x+6 < 1/3
-3x < 1/3-6
-3x < -17/3
x > 17/9
Answer:
circle b and it is bigger by 1 centimeter
Step-by-step explanation:
since circle b has a radius of 5 and radius is have of the diameter you have to do 5+5 to get the diameter when you do that you get 10 and then you have to subtract circle a diameter which is 9 from circle b diameter which is 10 so 10-9 is 1
