Step-by-step explanation:
<u>Formula:</u>

r represents the radius.
The radius is 1/2 of the diameter.
Since 1/2 of 16 is 8, 8 is our radius.
<u>Substitute:</u>

<u>Solve:</u>


Answer:
B
Step-by-step explanation:
formula s =4*pi*r^2
s=4(3.14)(3^2)
s = 12.56(9)s= 113.04
The order is:
1/5, 0.35, 12/25, 0.5, and 4/5.
Answer:
f(-6) = 3
Step-by-step explanation:
In order to find the value of f(-6), we need to find what y-value appears associated with x = -6 according to the graph resented.
Therefore, go to x = -6 on the horizontal axis (six units to the left of the origin of the coordinate system), and find at what value of the y-axis the vertical grid passing through x = -6 intercepts the graph of the function.
That is indicated by a red dot in the attached image.
We see therefore that for x = -6 the y-value that the graph of the function shows in the vertical scale is "3".
Then, f(-6) = 3
