The formula to solve for this would be pi(r^2)xheight. Essentially what this formula does is it takes the are of the base (pi x r^2) and multiplies it by the height of the cylinder to find how many times the base can stack on itself until it reaches the top. This formula of base are times height works for all prisms with two bases. Here are the steps to solve:

1) plug in the values
- pi(15^2) x 45

2) solve for the base area of one of the circles
- pi(15^2)=225pi

3) multiply the base area by the height
- 225pi x 45 = 10,125pi

4) final answer: the tank can hold 10,125pi cubic feet of water

Can someone help me pls!
eduard

This question is about how transformations can affect graphs.

First, we'll want to get rid of that -4 on the function of F.

So we can reflect the function over the y-axis and then compress it by a factor of 4 to make the graph x^2.

Then we can move the graph over to the left 3 because the c value is positive, meaning that we move the graph over to the left.

Finally, we can move the function of by \frac{2}{3} because the d value is positive, meaning that we move the graph up.

Hope this helps.

頑張って!

A small town's raffle has 85 entries and 3 gift baskets that three different people could win. What is the probability of winnin
mr_godi [17]

Answer:

<h2>0.035</h2>

Step-by-step explanation:

This problem is on probabilty since there are a number of entries to be selected from which are 85 entries, the chances of winning one of the prices if selected is

the number of entries you have/ total number of entries

given that the total entry is 85

and that you have one entry

Since there are three gift baskets you have three chances to win one.

hence there will be a total of three draws, and after each draw, there won't be a replacement of the previous winner (as the winners are three distinct persons).

Hence the probability of winning a draw for the gift basket is  

=1st draw+2nd draw+3rd draw

= 1/85+1/84+1/83

= 0.0117+0.0119+0.012

= 0.035
