The answer is 4pi because the formula to find the circumference is C = 2 pi r. this question is asking for the terms of pi which means you remove the pi from the formula and solve it with out it. the radius is 2 because of the 2 units on the graph is halfway of the circle. you would just multiply 2 x 2 and get 4. after that you put the pi on the end of the 4. so the answer is C. (4pi)

Answer:
0 (zero)
Step-by-step explanation:
Plug in the variable for -4 and solve
y= 2(-4)2-4(-4)
y= -8(2)-4(-4)
y=-16+16
y=0
Answer:

Step-by-step explanation:
The slope-intercept form of equation of a linear function:

m - slope
b - y-intercept
We have the slope m = 4/5 and the y-intercept b = -6. Substitute:

Answer:
960
Step-by-step explanation:
x = 0.6x + 384
Subtract 0.6x from both sides.
0.4x = 384
Divide both sides by 0.4
x = 960
