Best ResponseYou've already chosen the best response.0I tried to divide 80 by 26 and then multiplying that answer by 180, but it didn't work out so well...

Best ResponseYou've already chosen the best response.0now we have to convert 80 degree to radians

Best ResponseYou've already chosen the best response.0no this time we are converting the other way \[80\times \frac{\pi}{180}\]

Best ResponseYou've already chosen the best response.0that comes out to be \[\frac{4\pi}{9}\] radians

Best ResponseYou've already chosen the best response.0Do we multiply that by 180?

Best ResponseYou've already chosen the best response.0we want \(a\) the arc length the radian measure is arc length over the radius so \[\frac{a}{26}=.4\pi=1.4\] so \[a=26\times 1.4\]

Best ResponseYou've already chosen the best response.0\[a=26\times \frac{9}{4}\pi=11.5\pi\]

Best ResponseYou've already chosen the best response.0If the length of an arc is 12pi inches and the radius of the circle is 10 inches, what is the measure of the arc? a) 216 degrees b) 270 degrees c) 288 degrees

Best ResponseYou've already chosen the best response.0the radian measure is \[\frac{12\pi}{10}=1.2\pi\]

anonymous

Best ResponseYou've already chosen the best response.0then \[1.2\pi\times \frac{180}{\pi}=1.2\times 180=216\]
