Hello from MrBillDoesMath!

Answer:

r = C/6.28

Discussion:

Note that C = 2 * Pi * r is the exact formula. As Pi is approximately 3.14, the given formula, C = 2 (3.14) r, is an approximation. Solving it for r:

C = 2(3.14) r => as 2 * 3.14 = 6.28

C = 6.28 r => divide both sides by 6.28

r ( 6.28/6.28) = C/6.28 => as 6.28/6.28 = 1

r = C/6.28

Thank you,

So,

All we have to do is multiply all three dimensions together.

First, convert all fractions into improper fractions.

$3 \frac{1}{5}--\ \textgreater \ \frac{16}{5}$

$1 \frac{3}{4} --\ \textgreater \ \frac{7}{4}$

$2 \frac{1}{4} --\ \textgreater \ \frac{9}{4}$

Now multiply the fractions together.

<span> $\frac{16}{5}*\frac{7}{4}*\frac{9}{4}= \frac{2*2*2*2*3*3*7}{2*2*2*2*5}$
</span>
$\frac{3*3*7}{5}--\ \textgreater \ \frac{63}{5}\ or\ 12 \frac{3}{5}\ ft.^3$

The correct option is C.
