Answer: 6702.1

Explanation:
Volume of cylinder = πr^2h
= π(8^2)25
= 1600 π

Volume of cone = πr^2(h/3)
= π(8^2)(25/3)
= π (64)(25/3)
= (1600 π)/3

Add these two numbers
= 1600 π + (1600 π)/3
= (4800 π+ 1600 π)/3
= 6400 π/ 3
=6702.06≈6702.1

Answer:

Volume of the entire silo = 5428.67 ft³

Step-by-step explanation:

Here we need to add volume of cylinder to volume of cone.

\texttt{Volume of cylinder =}\pi r^2h,

Where r is the radius of cylinder and h is the height of cylinder.

\texttt{Volume of cone =}\frac{1}{3}\pi r^2h

Where r is the radius of cone and h is the height of cone.

Radius of cylinder = 8 feet

Height of cylinder = 25 feet

Radius of cone = 8 feet

Height of cone = 6 feet

Substituting

             \texttt{Total volume = Volume of cylinder + Volume of cone}\\\\\texttt{Total volume =}\pi \times 8^2\times 25+\frac{1}{3}\times \pi \times 8^2\times 6=5428.67ft^3

Volume of the entire silo = 5428.67 ft³

A baseball team has 13 players; how many possible batting orders can the coach make if there are 9 players in the batting lineup
mote1985 [20]
The answer to this question would be: <span>C. 259,459,200 
</span>To answer this question, you will need to understand how to use permutation in probability. In this question, there will be 9 people out of 13 people that make an order for batting. In this case, if same people used but the batting order is different that could be considered different ways. Then the answer would be: P(13,9)= 13! / (13-9)!= 13!/4!= <span>259,459,200 </span>

Select the correct answer. The sum of Sally and Beth's age is 60. Six years ago, Sally was 3 times as old as Beth. What are thei
erastova [34]

Answer:

B. Beth's age is 18 years, and Sally's age is 42 years.

Step-by-step explanation:

You can solve this question in a couple of different ways. First, you can use process of elimination. You know that Sally is older than Beth because she has to be 3 times older 6 years ago, so you can get rid of options C and D because they both show Beth as being older. Now you only have A and B, and you can use a different process. Now from just looking at it, you can tell that A actually already shows Sally as 3 times Beth's age, 15 * 3 = 45. If you go to B, you can go ahead and subtract 6 from 18 (Beth's age) which will give you 12, and then multiply that by 3 to get 36. Now if you take 42 (Sally's age) and subtract 6 from it as well, you will get 36. This means that is lines up. To simplify, you are subtracting 6 from both 18 and 42, and then you are multiplying the lower number by 3 to see if it gets to the bigger number.

Hope this helped ^-^

HELP ME!!! ITS DUE TOMMOROW!! Find the largest value of $r$ such that $6r^2+7r+8=6$.
Alex787 [66]
First you need to see that this is a quadratic. I need.to put all of the values on one side of equation to see what I got.
6r^2 + 7r + 8 = 6
6r^2 + 7r + 2 = 0

Now this one is difficult to factor so i will use quadratic equation:
[-b (+-) sqrt (b^2 - 4ac)] / (2a)

we know that a b and c are in a quadratic at these positions.
ax^2 + bx + c

so
[-7 (+-) sqrt (7^2 -(4)(6)(2)] / (2) (6)
[-7 (+-) sqrt (49 - 48)] / 12
[-7 (+-) 1] /12

split into the + and - for 2 answers
(-7 + 1) / 12
-6/12
-1/2

And
(-7 -1) /12
-8 / 12
-2/3

those are.the 2 answers

But but it says largest so -1/2
