can somebody please help me through this question? I totally forgot everything over the summer, and I'm in AP algebra so i would
really appreciate catching up. Thanks dudes !

Do you know what the right answer is? I haven't done this stuff since high school. So, I could be wrong. I thought I'd warn you in advance. ;)
I am not sure if this is how you do the problem, but this is how I did it:
I plugged in x-values to each equation until I found the one that fit the graph. The shading I believe represents the side of the line that we would like to have a y-coordinate on. I attached a screenshot of my work. Hope it makes sense!

Answer:
A = 907.46
Step-by-step explanation:
C = πd
34π = πd
d = 34
r = 17
A = = 3.14(
) = 3.14(289) = 907.46
The angular velocity is 16 radians per second
<u>Solution:</u>
The angular velocity of point is given by formula:
Where,
w is the angular velocity in radians
v is the linear velocity
r is the radius
Given that diameter of wheel is 10 feet
Thus radius is 5 feet
A point on the rim of a wheel moves with a velocity of 80 feet per second
Linear velocity = v = 80 feet per second
Therefore, angular velocity is given as:
Thus angular velocity is 16 radians per second
