Find the Angle in Radians Through Which a Pendulum Swings If Its Length is 75 Cm and the Tip Describes an Arc of Length 15 Cm - Mathematics

Find the angle in radians through which a pendulum swings if its length is 75 cm and the tip describes an arc of length 15 cm

Solution

We know:
Radius = 75 cm
Length of the arc = 15 cm
Now,
$\theta = \frac{\text{Arc }}{\text{Radius}}$
$= \frac{15}{75}$
$= \frac{1}{5}\text{ radian }$

Is there an error in this question or solution?
