Answer:
The volume of the water in the pool is 1,017 cubic feet
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
![V=\pi r^{2} h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7D%20h)
we have
----> the radius is half the diameter
Remember that
![1\ ft=12\ in](https://tex.z-dn.net/?f=1%5C%20ft%3D12%5C%20in)
so
![6\ in=6/12=0.5\ ft](https://tex.z-dn.net/?f=6%5C%20in%3D6%2F12%3D0.5%5C%20ft)
To find out the height of the water, subtract 0.5 feet from the height of the swimming pool
![h=4.5-0.5=4\ ft](https://tex.z-dn.net/?f=h%3D4.5-0.5%3D4%5C%20ft)
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
Find the volume of the water
![V=(3.14)(9^{2})(4)](https://tex.z-dn.net/?f=V%3D%283.14%29%289%5E%7B2%7D%29%284%29)
![V=1,017\ ft^3](https://tex.z-dn.net/?f=V%3D1%2C017%5C%20ft%5E3)
Step-by-step explanation: To evaluate functions substitute the given number or expression function's variable.
Hi there!
![\large\boxed{\text{ 10.5 in}^3}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%5Ctext%7B%2010.5%20in%7D%5E3%7D%7D)
Begin by solving for the area of the base:
A = 1/2 (bh)
Thus:
A = 1/2(2 · 1.5) = 1.5 in²
Multiply by the depth to find the volume:
A = 1.5 × 7 = 10.5 in³
Split the second term in 3a^2 - 8a + 4 into two terms
3a^2 - 2a - 6a + 4 = 0
Factor out common terms in the first two terms, then in the last two terms.
a(3a - 2) -2(3a - 2) = 0
Factor out the common term 3a - 2
(3a - 2)(a - 2) = 0
Solve for a;
a = 2/3,2
<u>Answer : B. (2/3,2)</u>
Answer:
A: 8
B: 96
I'm not sure on C, sorry.
