Question

find the angle between hour hand and minute hand in circular measure at half past 4

Answer 1

The area which will be covered is this:

12  is 6/12 = 1/12

Now we will try to find the angle which is covered by a minute hand:

1/2 × 2π = π

and at the half past four the portion which will be covered is 12  is 4.5/12 = 3/8

Now the angle covered by the hour hand:

12  is 3/8 × 2 π = 3π/4

Now the angle at the minute hand, hour hand and half past four is

π−3π/4=π/4.

Answer 2

Answer:

ITS 45 DEGREE IN CIRCULAR ITS PIE/ 3 3-6 on the clock makes 1π=90°

There are three subparts to it as 3-4, 4-5 ,5-6

Thus, π/3
