The volume of a cylinder (vc) is given by:
![v_c = \pi r^2h](https://tex.z-dn.net/?f=v_c%20%3D%20%5Cpi%20r%5E2h)
In this case, you are given the diameter, and the radius is diameter/2. So, it will be:
![r = \frac{17.5}{2} = 8.75](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B17.5%7D%7B2%7D%20%3D%208.75%20)
Now, you have everything given to plug into the equation. Let's do that:
![v_c = (3.14)(8.75)^2(24.5)](https://tex.z-dn.net/?f=v_c%20%3D%20%283.14%29%288.75%29%5E2%2824.5%29)
Simplify and solve to get:
![v_c = 5889.95](https://tex.z-dn.net/?f=v_c%20%3D%205889.95%20)
So, your answer is
5889.95 ft³.
Answer:
yes it is yee cause the negatives cancel out
Answer:
Number 1 and Number 4
Step-by-step explanation:
By factoring, you can figure out the roots (x = -2 or x = 2)...
1. x^2 - 4 = 0
--> (x + 2)(x - 2) = 0
--> x = -2, x = 2
2. x^2 + 4 = 0
--> factors weirdly, so I won't write it. You'd have to use the quadratic formula.
3. 3x^2 + 12 = 0
--> 3 (x^2 + 4) = 0
--> factors weirdly (same as above)
4. 4x^2 - 16 = 0
--> 4 (x^2 - 4) = 0
--> 4 (x+2) (x-2) = 0
--> x = -2, x = 2
5. 2 (x-2) 2 = 0
--> x = 2
We take 2 marbles from 20 marbles and the total ways is 20x19:2=190
But we need only 2 red marbles and the ways is 14x13:2=91
And finally we do the division 91:190=91/190 is the probability we need
9800 - 7400 = 2400 feet
11 am - 7 am = 4 hours
2400 / 4 = 600 feet per hour
