Answer:

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

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
C=2\pi r

The radius is r=8 cm


C=2* 8* \pi


C=16\pi

i.e. in 1 minute it cover
16\pi

In 10 minutes it cover
16\pi* 10

In 10 minutes it cover
160* 3.14

In 10 minutes it cover
502.4

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