Answer:
6.42 x 10^-8
Step-by-step explanation:
Answer:
(y - 2)(y - 6)
Step-by-step explanation:
To factorise
Consider the factors of the constant term (+ 12) which sum to give the coefficient of the y- term (- 8)
The factors are - 2 and - 6
since - 2 × - 6 = + 12 and - 2 - 6 = - 8, hence
y² - 8y + 12 = (y - 2)(y - 6)

The answer is
<h2>134 ft³</h2>
Step-by-step explanation:
Volume of a hemisphere is given by
![V = \frac{2}{3} \pi {r}^{3}](https://tex.z-dn.net/?f=V%20%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20%5Cpi%20%20%7Br%7D%5E%7B3%7D%20)
where
r is the radius of the hemisphere
From the question
diameter = 8 ft
radius = 8/2 = 4 ft
Substitute the value into the above formula and solve
![V = \frac{2}{3} ( {4})^{3} \pi \\ = \frac{2}{3} \times 64\pi8 \\ = \frac{128\pi}{3} \: \: \: \: \: \: \: \\ = 134.0412](https://tex.z-dn.net/?f=V%20%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20%28%20%7B4%7D%29%5E%7B3%7D%20%5Cpi%20%5C%5C%20%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20%20%5Ctimes%2064%5Cpi8%20%5C%5C%20%20%3D%20%20%5Cfrac%7B128%5Cpi%7D%7B3%7D%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%20%5C%5C%20%20%3D%20134.0412)
We have the final answer as
<h3>134.0 ft³ to the nearest tenth</h3>
