Question

The length of the minute hand of a clock is 14cm . Find the area swept by the minute hand is 5

Answer 1

Answer:

Step-by-step explanation:

Center of angle of sector =360/12=30

Radius of circle =14cm

Area of sector =22/7x14x14x30/360

153/3=51.3333......

Answer 2

The swept area of a clock hand is always circular area.

And the radius of that circular area is the length of the given clock hand.

And according to data mentioned in the question:

The swept area in one minute will be:

=2.π.14² [area of a circle is 2πr]

=1232 cm²

The swept area in five minutes will be:

=5×1232 cm²

=6160 cm² (answer)
