b. 6280 cubic feet

Step-by-step explanation:

Volume:

The volume of the prism, which has a cylindrical base, with radius r and height h, is given by:

$V = \pi r^2h$

Radius:

The radius is 20, so r = 20

The manufacture recommends that it be filled to within 1 foot of the rim.

Height of 6 - 1 = 5, so h = 5

Then

V = 3.14*(20)^2*5 = 6280

So the volume is 6280 cubic feet, and the correct answer is given by option b.

Given:

Fractions $\dfrac{1}{9},\dfrac{2}{9},\dfrac{3}{9}$ etc.

To find:

What happens with the “ninth” fractions.

Solution:

We have, the values of $\dfrac{1}{9},\dfrac{2}{9},\dfrac{3}{9}$ are

$\dfrac{1}{9}=0.11111...$

$\dfrac{2}{9}=0.22222...$

$\dfrac{3}{9}=0.33333...$

Clearly we can spot a pattern, because after decimal the numerator digit of fraction is repeating.

Similarly,

$\dfrac{9}{9}=0.99999...$

Therefore, the decimal value of $\dfrac{9}{9}$ is 0.99999..., which is approximately 1.
