Answer 1

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 $C=2\pi r$

The radius is r=8 cm

$C=2\times 8\times \pi$

$C=16\pi$

i.e. in 1 minute it cover  $16\pi$

In 10 minutes it cover  $16\pi\times 10$

In 10 minutes it cover  $160\times 3.14$

In 10 minutes it cover  $502.4$

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