Answer:
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;
[tex]C = 2\pi r[/tex]
[tex]C = 2 \cdot \pi \cdot 8 = 16 \pi[/tex]
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 = [tex]10 \times 16 \pi = 160 \pi =160 \times 3.14 = 502.40 cm[/tex]
