the length of the pendulum is 1 meter.
\n" ); document.write( "the pendulum swings through an angle of 360 degrees to make the circumference of the circle.
\n" ); document.write( "the formula for the circumference of the circles is 2 * pi * r.
\n" ); document.write( "when r = 1, the circumference is equal to 2 * pi.
\n" ); document.write( "when the pendulum swings through an angle of 60 degrees, then it is swinging through an arc that is 60/360 = 1/6 * the circumference of the circle.
\n" ); document.write( "the pendulum therefore swings through an arc of 1/6 * 2 * pi = 2/6 * pi = 1/3 * pi.
\n" ); document.write( "your answer is that the pendulum swings through a distance of 1/3 * pi meters from one extreme point to another.\r
