Answer:

C.) 19.1

Step-by-step explanation:

$C=2$ π $r$

$120=2*3.14*r$

Divide by pi

$\frac{120}{3.14}=2r\\ \\38.22=2r$

Divide both sides by 2

$\frac{38.22}{2} =\frac{2r}{2} \\\\19.11=r\\\\r=19.1$

Done.

How do I find the distance between (-2,5) and (22,12)

jok3333 [9.3K]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-2}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{22}~,~\stackrel{y_2}{12})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[22-(-2)]^2+[12-5]^2}\implies d=\sqrt{(22+2)^2+(12-5)^2} \\\\\\ d=\sqrt{24^2+7^2}\implies d=\sqrt{625}\implies d=25$

True Or False?

Electromagnets are devices that create a magnetic field through the application of electricity. Strong electromagnets are used to lift, move and drop heavy objects, such as vehicles. Electromagnets have advantages over permanent magnets. When the current is switched off, the electromagnet will lose its magnetism. The car will fall back to earth and we need that when we move cars in a junkyard. With a regular ( permanent ) magnet it would be much harder to do.
