The second hand of a clock is 8 cm long what is the distance of the tip of the second hand travel in 10 minutes

The distance travelled by tip of second hand in 10 minutes is 502.4 cm

Solution:

Length of second hand = 8 cm long

In one revolution it travels a circumference of  a circle of which radius is 8 cm

The circumference of circle =

We are aksed to find the distance of the tip of the second hand travel in 10 minutes

Second hand complete 1 revolution in 1 minute.

Therefore, in 10 minutes it revolves 10 revolution,

In 1 revolution tip of second covers = 16π

Hence distance travelled is given as:

We know that π is a constant equals to 3.14

Thus the distance travelled by tip of second hand in 10 minutes is 502.4 cm

502.4
