What is the formula for finding circumference

C=2 πr which is the formula for circumference

A

Step-by-step explanation:

$3\left(1-2x\right)=\frac{1}{4}\left(6x+9\right)\quad:\quad x=\frac{1}{10}\quad\left(\mathrm{Decimal}:\quad x=0.1\right)$

3\left(1-2x\right)=\frac{1}{4}\left(6x+9\right)

$3\left(1-2x\right)$

$\mathrm{Apply\:the\:distributive\:law}:\quad\:a\left(b-c\right)=ab-ac$

$a=3,\:b=1,\:c=2x$

$=3\cdot\:1-3\cdot\:2x$

=3-6x

3-6x=\frac{3}{2}x+\frac{9}{4}

3-6x-3=\frac{3}{2}x+\frac{9}{4}-3

-6x=-\frac{3}{4}+\frac{3}{2}x

-6x-\frac{3}{2}x=-\frac{3}{4}+\frac{3}{2}x-\frac{3}{2}x

-\frac{15}{2}x=-\frac{3}{4}

2\left(-\frac{15}{2}x\right)=2\left(-\frac{3}{4}\right)

-15x=-\frac{3}{2}

\frac{-15x}{-15}=\frac{-\frac{3}{2}}{-15}

x=\frac{1}{10}
