Answer:

44580 inches

Step-by-step explanation:

Given, D (diameter)= 22 inches

Therefore, r (radius)= 22/2= 11 inches

Volume= $\frac{4}{3}$ ×π×r³

= $\frac{4}{3}$ ×3.14×22×22×22

=44579.626 inches

=44580 inches

What is the diameter of a hemisphere with the volume of 74466

stepladder [879]

$\textit{volume of a hemisphere}\\\\ V=\cfrac{1}{2}\cdot \cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ V=74466 \end{cases}\implies 74466=\cfrac{1}{2}\cdot \cfrac{4\pi r^3}{3} \\\\\\ 74466=\cfrac{2\pi r^3}{3}\implies 223398=2\pi r^3\implies \cfrac{22398}{2\pi }=r^3\implies \cfrac{111699}{\pi }=r^3 \\\\\\ \sqrt[3]{\cfrac{111699}{\pi }}=r~\hfill \stackrel{\textit{diameter = 2r}}{2\sqrt[3]{\cfrac{111699}{\pi }}\implies \sqrt[3]{\cfrac{893592}{\pi }}}~~ \boxed{\approx~~65.77}$

Which of the following is a solution of x^2 + 4x = −8?

8090 [49]

X²+4x+8=0
use the quadratic formula: (sorry cannot type it here)
√(b²-4ac)=√(4²-4*1*8)=√(16-32)=√(-16)=+/- 4i
x=(-4+4i)/2 or (-4-4i)/2
x=-2+2i or x=-2-2i
the answer is A
