The minute hand on a watch makes a full rotation each hour. In 30 minutes, the minute hand makes half of a full rotation. a. In how many minutes does the hand make 1/6 of a rotation b. In how many minutes does the hand make 1/6 of half a rotation? c. What fraction of an hour is 1/6 of half a rotation? d. How many degrees has the minute hand moved in 1/6 of a half rotation

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
