Marta is making two different charms for necklace one charm has a 1 cm diameter and a 3.14 cm circumference of a similar charm h

EastWind [94]

From what I can pick up from your problem statement, you want to know "a similar charm has a diameter of 4 cm what is the circumference." Please, would you use proper punctuation in your writing, for greater clarity:

"A similar charm has a diameter of 4 cm. What is the circumference?"

The formula for the circumference of a circle, when the diameter is known, is

C= $\pi$ d or C=pi*d

In this case, with diamter 4 cm, the circumference, C, is 4pi cm.

2-sin^2x=2cos^2(x/2)

nadezda [96]

$2-\sin^2x=2\cos^2\dfrac x2$
$1+\cos^2x=1+\cos x$
$\cos^2x-\cos x=0$
$\cos x(\cos x-1)=0$

and this has solutions of $x=\dfrac{n\pi}2=\dfrac{(2k+1)\pi}2$ and $x=n\pi=2k\pi$ where $k\in\mathbb Z$ .
