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

Academic Mathematics NCERT Class 7

From the question, it is given that,

Length of the minute hand of the circular clock$ = 15\ cm$

Then, Distance traveled by the tip of a minute hand in 1 hour $=$ circumference of the clock

$=2\pi r$

$=2\times 3.14\times 15$

$=94.2\ cm$
