Question

A pendulum swings through an angle of 300

and describes an arc 17.6 cm in length.

Find the length of pendulum.​

Answer 1

Answer:

33.1584 cm

Step-by-step explanation:

l = rФ, where Ф is angle in radians

17.6 = (5/3π) x r

r = 3 x 3.14 x 17.6 / 5 = 33.1584 cm

Therefore 33.1584 cm is the length of the pendulum.
