Best ResponseYou've already chosen the best response.0set up a proportion with the ratio of the angle to 360 on one side, equalling the unknown arc length over 2pi*r

Best ResponseYou've already chosen the best response.2or you can use arc length = radius * angle in radians

Best ResponseYou've already chosen the best response.0angle's in degrees tho

Best ResponseYou've already chosen the best response.2radians = degrees * pi/180

Best ResponseYou've already chosen the best response.0proportion is easier don't bother messing with radians

Best ResponseYou've already chosen the best response.2well the above is also useful to know

Best ResponseYou've already chosen the best response.0How do I find the radius?

Best ResponseYou've already chosen the best response.2have you got the answer

Best ResponseYou've already chosen the best response.0How do I get the radius when I am given the diameter?

Best ResponseYou've already chosen the best response.2by prossi's method we have 42/ 360 = x / 2pi * 15 or using radians x = 15 * 42 * pi/180

Best ResponseYou've already chosen the best response.2radius = half of the diameter

Best ResponseYou've already chosen the best response.0I got it, It's 10.99 feet

Best ResponseYou've already chosen the best response.2i think the radians method is slightly easier

Best ResponseYou've already chosen the best response.0Me too, that's the one I used

Best ResponseYou've already chosen the best response.2all you need remember is that pi radians = 180 degrees

welshfella

Best ResponseYou've already chosen the best response.2so to convert degrees to radians you multiply by pi/180 and for the reverse you multiply by 180/pi
