Answer:

The distance the tip of the second hand travels in 10 minutes is 502 cm.

Step-by-step explanation:

Given : The second hand on a clock is 8 cm long.

To find : What is the distance the tip of the second hand travels in 10 minutes?

Solution :

The circumference of clock is [tex]C=2\pi r[/tex]

The radius is r=8 cm

[tex]C=2\times 8\times \pi[/tex]

[tex]C=16\pi[/tex]

i.e. in 1 minute it cover  [tex]16\pi[/tex]

In 10 minutes it cover  [tex]16\pi\times 10[/tex]

In 10 minutes it cover  [tex]160\times 3.14[/tex]

In 10 minutes it cover  [tex]502.4[/tex]

Therefore, the distance the tip of the second hand travels in 10 minutes is 502 cm.
