Question

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

Answer 1

Step-by-step explanation:

Length of minute hand= 14 cm

Therefore, radius of the clock= 14 cm

Area of clock=πr^2

=π×14×14

=616 cm^2

Therefore, in 60 mins,

Area swept by minute hand=616cm^2

Area swept by minute hand in 1 minute= 616/60

Area swept by minute hand in 5 minutes=(616/60)×5

=616/12

=154/3

=51 1/3 cm^2 or 51.33 cm^2

Hope this helps you.
