Question

Through how many radians will the hour hand on a clock rotate in (a) 13 hr? In (b) 5 hr? (a) In 13 hr, the hour hand on the clock will rotate radians. (Type an exact answer in terms of a. Type an integer or a simplified fraction.) (b) In 5 hr, the hour hand on the clock will rotate radians. (Type an exact answer in terms of . Type an integer or a simplified fraction.)

Answer 1

@ 13hr . Assume clock 18 12 hours 'Clock rotate 360° for 12 hours I house e 360° - 30 12 13 hourra So 13X30 = 390° degrees into radians 390 T 1311 180° 6

hand on In 13 hr, the hour The clock will rotate 13 radians. b er hr will rotate 511 radiaus. In shr, 5x30 = 150 degrees into radiaus 150 x Ecole 180 the hour hand on the 6
