Question

the minute hand of a circular clock is 14cm long how far does the tip of the minute hand move in 3 days?​

Answer 1

Answer:

ok.....so your question seems to be quite easy

consider the clock to be a circle with minute hand as it radius.

for one hour the clock rotates 360 degree ... which is 2π radians

so we have the equation arc length = radius × angle covered by radius.

here from your information we can say in one hour the minute hand would cover 14*2π = 28π cm

there are 24 hours a day

72 hours in 3 days

therefore do

72*28π which gives approximately 6330 cms =====> 6.3 m

Answer 2

Answer:

The tip of the minute hand move in 3 days = 6336 cm
