Answer:
First, let's work out the V of container A and B
V_A = pi x (diameter/2)^2 x height = pi x (26/2)^2 x 14 = 2366 pi (ft3)
V_B = pi x (diameter/2)^2 x height = pi x (18/2)^2 x 15 = 1215 pi (ft3)
After pumping water from container A to container B until B is full:
The empty space inside container A would be:
V_empty = V_A - V_B = 2366 pi (ft3) - 1215 pi (ft3) = 1151 pi (ft3) = ~3615.97 (ft3)
This is true central angles are equal to the measure of their intercepted arc

Why do you want people's number
Answer:
<em>28 dvds were given if 455 people visit the store.</em>
Step-by-step explanation:
4 out of every 65 people who visited the store will receive a free dvd.
Suppose, dvds were given if 455 people visit the store.
Now, according to the <u>ratio of "people who got dvd" to "total number of people"</u> , the equation will be.........
So, the number of dvds given is 28.
