2x/7 divides by 4y/14?

Sonbull [250]

Remember that $\frac{\frac{a}{b}}{\frac{c}{d}}=(\frac{a}{b})(\frac{d}{c})=\frac{ad}{bc}$

try and simpliy each first
4y/14=(2/2)(2y/7)=2y/7

so 2x/7 divided by 2y/7
$\frac{\frac{2x}{7}}{\frac{2y}{7}}=(\frac{2x}{7})(\frac{7}{2y})=\frac{(2x)(7)}{(2y)(7)}$ = $\frac{14x}{14y}=\frac{x}{y}$

Find the volume of the cylinder. Round your answer to the nearest tenth.

Ipatiy [6.2K]

Step-by-step explanation:

$r = 6 \: in \\ h = 7 \: in$

Volume Of Cylinder

$= \pi \: r {}^{2} h$

$= \frac{22}{7} \times 6 \times 6 \times 7 \\ \\ = 22 \times 36 \\ = 11 \times 2 \times 36 \\ = 11 \times 72 \\ = 792$

thus the volume of cylinder is 790 cubic inches (nearest tenth)
