Question

The length of the seconds hand of a wall clock is 7 cm a) FIND THE DISTANCE COVERED BY THE TIP OF THE SECOND HAND IN 10 MINUTES. B) FIND THE AREA SWEPT BY THE SECOND HAND IN10 MINS .​

Answer 1

Step-by-step explanation:

The path traveled by the tip of the minute hand over the course of one hour is a circle of radius r=6. The circumference of that circle is

C=2πr=2π⋅6=12π.

The tip has traveled 10 inches since noon, so the fraction of the circle traveled is 1012π,

and the number of minutes that have expired since noon is 1012π⋅60≈16.

Therefore, to the nearest minute, the time is 12:16.
