Answer:
12π
Step-by-step explanation:
Volume of the cone is πr^2 * h / 3
r = 3
h = 4
9π * 4 / 3 = 12π
Answer:
57
Step-by-step explanation:
The player has a 1/4 chance of drawing any of the 4 prizes. This means that the probability of drawing a prize of $4 is 1/2 because there are 2 prizes worth of $4. The probability of drawing a prize of $20 is 1/4 and the probability of drawing a prize of $200 is also 1/4. To find the fair price of the game, we have to calculate the expected value that the player will gain. This can be obtained by multiplying any possible value of a price for the probability of drawing a prize of that value and adding all the obtained values togueter. Thus, the fair price of the game is
![4 * \frac{1}{2} + 20 * \frac{1}{4} + 200 * \frac{1}{4} = 57](https://tex.z-dn.net/?f=%204%20%2A%20%5Cfrac%7B1%7D%7B2%7D%20%2B%2020%20%2A%20%5Cfrac%7B1%7D%7B4%7D%20%2B%20200%20%2A%20%5Cfrac%7B1%7D%7B4%7D%20%3D%2057%20)
