Best ResponseYou've already chosen the best response.1\(\textit{sector of a circle}=\cfrac{\theta \pi r^2}{360}\qquad \begin{cases} r\to radius\\ \theta\to \textit{angle, in degrees} \end{cases}\)

Best ResponseYou've already chosen the best response.0can you help me break this down? @jdoe0001

Best ResponseYou've already chosen the best response.1hmmm well.. check what your "radius" is and check your angle then just plug and chug

Best ResponseYou've already chosen the best response.1hmmm need to check your PEMDAS notice, \(\textit{sector of a circle}=\cfrac{\theta \pi r^2}{360}\qquad \begin{cases} r\to radius\to &10\\ \theta\to \textit{angle, in degrees}\to &37 \end{cases} \\ \quad \\ \cfrac{37\cdot \pi \cdot 10^2}{360}\implies ?\)

Best ResponseYou've already chosen the best response.0thanks! could you help me with another? @jdoe0001 An angle measure of 82 degrees is equivalent to ____ radians. Round your answer to the nearest hundredth when necessary.

Best ResponseYou've already chosen the best response.1ok.. well.. how many say.... degrees in \(\pi\) radians?

Best ResponseYou've already chosen the best response.0would it be 82/3.14? im so confused

Best ResponseYou've already chosen the best response.1hmmm nope... well. check your Unit Circle, see how many degrees are in a \(\large \pi\) firstly

Best ResponseYou've already chosen the best response.1http://www.shelovesmath.com/wpcontent/uploads/2012/11/UnitCircle1.png < notice this Unit Circle so... hmm yes 180

Best ResponseYou've already chosen the best response.1\(\begin{array}{ccllll} degrees&radians \\\hline\\ 180&\pi \\ 82&x \end{array}\implies \cfrac{180}{82}=\cfrac{\pi }{x}\implies x=\cfrac{82\cdot \pi }{180}\)

Best ResponseYou've already chosen the best response.1anyhow, "x" is how many degrees are in 82 :)

Best ResponseYou've already chosen the best response.1or rather, how many radians are in 82 degrees

Best ResponseYou've already chosen the best response.1if I recall correctly, 1 radian is about 51 degrees so 82 is about 1.4, sure
