4% of ___ days is 56days

Kay [80]

We calculate this like this:

$\frac{4}{100} *x=56
$

where x is the desired number. 4 percent of x is 56
$\frac{4} *x=56*100
$

here i multiplied both sides by 100

$x= \frac{56*100}{4}
$

I divided both sides by 4, then on the left hand side only x is left!

$x= \frac{56*25}{4}
$

$x= 1400
$

The answer is 1400

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)
