Halla la medida del lado de un cuadrado cuya diagonal es de 14 cm

8_murik_8 [283]

Answer:

The length side of the square is $7\sqrt{2}\ cm$

Step-by-step explanation:

<u><em>The question in English is</em></u>

Find the measure of the side of a square whose diagonal is 14 cmd

Let

d ----> the diagonal of a square in cm

b ---> the length side of a square in cm

we know that

Applying the Pythagorean Theorem

see the attached figure to better understand the problem

$d^2=b^2+b^2$

$d^2=2b^2$

we have

$d=14\ cm$

substitute the given value

$14^2=2b^2$

solve for b

$196=2b^2$

$98=b^2$

take square root both sides

$b=\sqrt{98}\ cm$

simplify

$b=7\sqrt{2}\ cm$

Please help me in number 20 please I need it ASAP

Ad libitum [116K]

Answer:

$r=\sqrt{\frac{A}{\pi}}$

Step-by-step explanation:

Given:

The area 'A' of a circle with radius equal to 'r' is given as:

$A=\pi r^2$

In order to rewrite the given formula in terms of radius 'r', we need to isolate 'r'.

Dividing both sides by π, we get:

$\frac{A}{\pi}=\frac{\pi r^2}{\pi}$

As $\frac{\pi}{\pi}=1$ , the above equation becomes:

$r^2=\frac{A}{\pi}$

Taking square root both the sides, we get:

$\sqrt{r^2}=\sqrt{\frac{A}{\pi}}\\r=\sqrt{\frac{A}{\pi}}$

We neglect the negative result while taking square root as the radius can't be a negative number.

Thus, the formula for radius 'r' in terms of area 'A' is given as:

$r=\sqrt{\frac{A}{\pi}}$
