Segment AB is a diameter of the sphere.
diameter = AB = 16 in.
radius = r = (16 in.)/2 = 8 in.
Volume of a sphere:
V = (4/3) * pi * r^3
V = (4/3) * (22/7) * (8 in.)^3
The water inside the bowl occupies half of the bowl, so the volume of the water is half the volume of the bowl.
Volume of water:
V = (1/2)(4/3)(22/7)(8^3) in.^3
Answer: Second choice.
To represent the opposite of this number, if it is positive nineteen,
he would need to first take nineteen steps back to reach his original
position which in this case represents zero. He would then need to take
another nineteen steps backwards, to reach negative nineteen.

Answer:
16 students got an A
Step-by-step explanation:
Set up an equation to compare the ratio to the scores:
Cross multiply:
80 = 5x
Divide each side by 5:
x = 16
Now, check if 
16/8 = 2
40/8 = 5
The ratios are the same! Therefore, 16 students got an A!

Slope = (5 + 4)/(2 +1) = 9/3 = 3
y = mx + b
5 = 3(2) + b
b = -1
equation
y = 3x - 1
answer
y = 3x - 1
