Question

the minute hand clock is 14cm long find the area on the clock discribed by minute hand between 8:00am to 8:35am

Answer 1

it takes 35 minutes in covering 8 '00 to 8 '35

Answer 2

Answer:

As the minute hand takes 60 min to complete one round.

Then, it travels 1/60 rounds in 1 min

Similarly, it travels 35/60 rounds in 35 min

Now,

Area swept in 1 round = πr²

So

Area swept in 35/60 rounds

= πr²×35/60

=22/7 ×7²×35/60

=89.9 cm²
