Answer 1

502.40 cm

Explanation:

Hope this helps!

Answer 2

As per the statement:

Length of second hand = 8 cm long .

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

`C = 2\pi r`

`C = 2 \cdot \pi \cdot 8 = 16 \pi`

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

then;

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 traveled distance =
`10 * 16 \pi = 160 \pi =160 * 3.14 = 502.40 cm`
