♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

\frac{2}{9}  =  \frac{4}{x + 8}  \\

\frac{4}{x + 8}  =  \frac{2}{9}  \\

Inverse both sides

\frac{x + 8}{4}  =  \frac{9}{2}  \\

Multiply sides by 4

4 \times  \frac{x + 8}{4}  = 4 \times  \frac{9}{2}  \\

x + 8 = 2 \times 9

x + 8 = 18

Subtract sides 8

x + 8 - 8 = 18 - 8

x = 10

Done...

The area of circle is 770cm^2then find its circumfrence​
Gala2k [10]

Answer:

The circumference is 98.39 centimeters (rounded to 2 decimal places)

Step-by-step explanation:

The area of a circle has the formula  \pi r^2

The circumference of a circle has the formula  2\pi r

First, let's find r from area given:

\pi r^ 2= 770\\r^2 = \frac{770}{\pi}\\r=\sqrt{\frac{770}{\pi}} \\r=15.66

Now, we can use this value of r and plug in into the formula for circumference. Shown below:

2\pi (15.66)\\=98.39

The circumference is 98.39 centimeters (rounded to 2 decimal places)
