Create 3-d models of a cone and a cylinder. you can start out by using an empty can, a toilet paper tube, or a snow cone holder. (just make sure they are clean and dry.) the height of the cone and the radius of the base of the cone must be equal to the height of the cylinder and the radius of the base of the cylinder. if you cannot find two existing items that match these requirements, you can make one or both of the items yourself. now, once you have your cone and your cylinder, fill the cone completely with sand, small pebbles, peanuts, or any other substance that your model can hold. transfer the cone's contents to the cylinder, refilling the cone after each transfer. do this as many times as it takes to completely fill the cylinder.

a. how many times were you able to transfer the contents of the cone into the cylinder?

??is that namjoon i cant really see the profile picture you have lol ??

V cone = pi• radius ^2 • height/ 3  

V cylinder= pi• radius ^2. • height  

1) three times cone is smaller then cylinder that have the same radius and height

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
