What is the exact volume of the cone?base 7in
height 4in

PLEASE HELP ASAP

Answers

The volume formula of a cone is (1)/(3)  \pi  r^(2) h the r is the radius and h is the height.  However, if you multiply by pi, you will get an approximated volume of the cone.  So we will multiply like this for now. (1)/(3)  r^(2) h Don't worry, we'll use pi in the end.  

I'm going to assume that 7 inches is your radius.  We need to plug in 7 for r and 4 in for h into the equation. Once we do that, it will look like this. (1)/(3)  7^(2) 4

(1)/(3) means we will need to divide one by 3.  That gives us 0.33333... now we have to multiply by 7^(2) we get 16.33333...  now the last thing we need to do is multiply by 4, which is h.  We get 65.33333.  Add pi and you have your answer. 65.333333333 \pi

Jenna has a bag that contains 7 red marbles and 25 blue marbles. She selects a marble at random, and then, without replacing the first one, selects another marble at random.What is the probability that Jenna selects a blue marble and then a red marble? Round your answer to the nearest percent.



P(blue and red) ≈

Answers

Jenna has a bag that contains the following
 => 7 red marbles
=> 25 blue marbles.
She selects a marble at random, and then, without replacing the first one, selects another marble at random.
=> 7 + 25 = 32 marbles are there in all.
For blue marble 
=> 1/32 is the probability
For red 
=> 1/31 is the probability
or 
3%
So if we have a total of 32 marbles in the bag and the first pull we want a blue we can say the total number of favorable outcomes is 25/32 then to pull a red marble is 7/31 because one marble had been removed. 

25/32 x 7/31 = 0.176 So now we need to round to the nearest percent which would be 18% chance.
