Well if the data is related to 8 cm by 12cm(it means 4cm of radius and 12 of height)and you already have pi so what you need is to use the formula <span>V=π*r^2*(h/3) and replace the data. After you do this you can see that the closest is 339 cm3. Hope this helps a lot </span>
For Q2 it is just a simple matter of using a tree diagram for each possible outcome. So there are 4 black balls (B) and 2 white (W) and by using a tree diagram of the possible outcomes it comes to a 3 out of 5 points go to player 1 if B was drawn first and 2 go to player 2. If W was drawn first though, then player 1 gets 1 out of 5 points and 4 goes to player 2 and if you add up the probabilities at the end it comes to player 1 having a 14 out of 30 chance and player 2 having a 16 out of 30 chance therefore player 2 would have a better chance at winning and it isn't a fair game
Amazing i hope you have a spectacular day

Answer:
The equation for the speed of the train is: 162 = 3x
I think the speed of the train is 54 miles per hour
Step-by-step explanation:
We know that:
y = distance in miles
x = speed of train (miles/hour)
t = time traveled from the departing station (hours)
The equation: y = xt is given, we can therefore substitute the give values:
y = xt or tx
<u>162 = 3x</u> (This would be the equation)
Now we can find x by diving 3 on both sides of "="
162/3 = x
<u>54 = x</u> (This would be the speed of train)
Hope this helps!
