Question 17
The minute hand of a circular clock is 15 cm long. How far does the tip of the minute hand move in 1 hour?
$(Take\pi =3.14)$

Answer 1

In 1 hour, minute hand completes one round means makes a circle.
The radius of the circle (r) = 15 cm
Circumference of circular clock = $2\pi r$
$2\times 3.14\times 15=94.2cm$
Therefore, the tip of the minute hand moves 94.2 cm in 1 hour.
