Answer:
6 yd (Answer D)
Step-by-step explanation:
The formula for the volume of a cylinder of radius r and height h is
V = πr²h.
Here, this V = πr²h equals 144π yd³.
We must solve πr²h = 144π yd³ for r with the constraint that h = 4 yd.
Replacing h with 4 yd:
πr²(4 yd) = 144π yd³
Dividing both sides by π, we get:
4r² yd = 144 yd³
144 yd³
Solving for r²: r² = -------------- = 36 yd²
4 yd
Taking the square root of both sides, we get r = 6 yd (Answer D)

Answer:
Kendal will be 60 meters away from the library after 80 seconds and again after 100 seconds.
Step-by-step explanation:
6s -540 = 60 or 6s - 540 = -60
<u>First equation</u>
addition property of equality: 6s -540 + 540 = 60 + 540
simplify: 6s = 600
division property of equality: 6s/6 = 600/6
simplify: <em>s = 100</em>
<u>Second equation</u>
addition property of equality: 6s -540 + 540 = -60 + 540
simplify: 6s = 480
division property of equality: 6s/6 = 480/6
simplify: <em>s = 80</em>
