The height of a cone is equal to the diameter of the base.
(2x height, x radius)
what expression represents the volume of the cone, in cubic units?
a. 2/3 πx^3
b. 4/3 πx^2
c. 2πx^3
d. 4πx^3

we know that

the volume of a cone is equal to

where

r is the radius of the base of the cone

h is the height of the cone

in this problem we have

substitute in the formula

therefore

the answer is the option A

the naturalist literary movement was an extension of the realist literary movement, a movement that strove to portray life as it really was hope it

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.
