Mean: 9.75.
Median: 2.5.To find the mean.
Count the number of data points in your data set.
Sum up the total of your data set; add them all together.
Average = Mean = Sum/Number.The median of a data set can be found by arranging all the values from lowest to highest value and picking the one in the middle.
Answer:
847.8 sq meters
Step-by-step explanation:
Formula:
A= 2πrh + 2πr^2
A= 2(3.14)(9)(6) + 2(3.14)9^2
A= 339.12 + 508.68
A= 847.8
The volume of the remaining paint is:
V1 = (1/4) * (pi) * (r ^ 2) * (h)
Where,
r: radio
h: height
Substituting values we have:
V1 = (1/4) * (3.14) * (8 ^ 2) * (20)
V1 = 1004.8 cm ^ 3
The smallest can volume is:
V2 = pi * r ^ 2 * h
Substituting values:
V2 = (3.14) * 5 ^ 2 * h
Matching the volumes:
V2 = V1
(3.14) * 5 ^ 2 * h = 1004.8
Clearing h:
h = (1004.8) / ((3.14) * 5 ^ 2)
h = 12.8 cm
Answer:
The height of the smallest part of the paint is:
h = 12.8 cm
