1.	17.we warThe minute hand of a circular clock is 15 cm long. How far does the tip of the minutehand move in 1 hour. (Take = 3.14)ΕΧΑ
Answer» Inone 1 hour, the tip will complete one rotationradius = 15 cmso, distance = 2πr = 2×π×15 =30π cm = 94.2 cm In 1 hr the clock will complete 1 rotation length of the minute hand of clock=radius of clock=15cm circumference=2πr=2×3.14×15cm=94.2 therefore,the tip travels 94.2cm in 1 hour.

Answer»

Inone 1 hour, the tip will complete one rotationradius = 15 cmso, distance = 2πr = 2×π×15 =30π cm = 94.2 cm

In 1 hr the clock will complete 1 rotation

length of the minute hand of clock=radius of clock=15cm

circumference=2πr=2×3.14×15cm=94.2

therefore,the tip travels 94.2cm in 1 hour.
