If the amounts of rainfall in an area over a month are 1.7", 2.2", 0.5", 0.72",
and 1.1", what is the mean amount of rainfall in the area for the month?*

1.244"

Step-by-step explanation:

The mean is given by dividing the sum of the given numbers by the frequency. In this case, the frequency is 5 since we're given 5 rainfall data. The sum of the respective rainfall is equivalent to 1.7"+2.2"+0.5"+0.72"+1.1"=6.22"

Now dividing the above sum by frequency yields mean as follows

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
