In the circle, central angle AOB measures 45 degrees the arc is AB 3.14 cm long. How many cm is the radius?
\n" ); document.write( ":
\n" ); document.write( "Find the circumference
\n" ); document.write( "\"360%2F45\" * 3.14 = 25.12 cm
\n" ); document.write( "Find the radius
\n" ); document.write( "\"2%2Api%2Ar\" = 25.12
\n" ); document.write( "r = \"25.12%2F%282%2Api%29\"
\n" ); document.write( "r = 3.998 ~ 4 cm is the radius
\n" ); document.write( "
\n" );
