Of how many degrees, to the nearest degree? \n" ); document.write( "------ \n" ); document.write( "arc length = (theta)r where theta is a central angle in radians and \n" ); document.write( "r = radius. \n" ); document.write( "------------------------ \n" ); document.write( "Solve: \n" ); document.write( "11 cm = theta(5) \n" ); document.write( "theta = 11/5 radians \n" ); document.write( "---------------------------- \n" ); document.write( "Converting to degrees: \n" ); document.write( "(11/5)(180/pi) = (11*180/(5pi)) = 126.051 degrees \n" ); document.write( "================================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
