Question

A pendulum 25 cm long oscillates through an angle of 9°. what is the distance covered by the tip of pendulum two extreme position???

Answer 1

radius = 25 cm
distance = length of Arc

= (angle/360) x 2 (pie) x r
$= \frac{9}{360} \times 2 \times \pi \times 25$
$= \frac{5}{4} \pi$
$\frac{5}{4} \times \frac{22}{7}$
$\frac{110}{28}$
hope this helps..
