Volume of a cylinder:

V = πr²h

Container A

r = 10 ft, h = 11 ft
V = π*10²*11 = 1100π ft

Container B

r = 7 ft, h = 19 ft
V = π*7²*19 = 931π ft²

After pump out the container A has the level of:

1100π - 931π = 169π

Level % in the container A:

169π/1100π×100% = 15.4% rounded to the nearest tenth

Step-by-step explanation:

A person 6 feet tall standing 18 feet away a lamppost cast a 9 foot shadow.

than move 4 feet than total distance is 22 feet

According to trigonometry rule make 30 degree angle

$tan\left ( 30\ \right )^{o}=\frac{p}{b}$

$\left ( \frac{1}{\sqrt{3}} \right )=\left ( \frac{x}{18+4} \right )$

$x\sqrt{3}=22$

than

$x=\frac{22}{\sqrt{3}}$
