The second hand of a clock is 8 cm long what is the distance of the tip of the second hand travel in 10 minutes
<em><u>Answer:</u></em>
The distance travelled by tip of second hand in 10 minutes is 502.4 cm
<em><u>Solution:</u></em>
Length of second hand = 8 cm long
In one revolution it travels a circumference of a circle of which radius is 8 cm
The circumference of circle =
We are aksed to find the distance of the tip of the second hand travel in 10 minutes
Second hand complete 1 revolution in 1 minute.
Therefore, in 10 minutes it revolves 10 revolution,
In 1 revolution tip of second covers = 16π
<em><u>Hence distance travelled is given as:</u></em>
We know that π is a constant equals to 3.14
Thus the distance travelled by tip of second hand in 10 minutes is 502.4 cm
