Find and interpret the mean absolute deviation of the data.
1 answer:
Using it's concept, it is found that:
- The <em>mean absolute deviation</em> is of 26.
- It means that the values differ from the mean by an average of 26.
The mean of a data-set is given by the <u>sum of all observations divided by the number of observations</u>.
The mean absolute deviation of a data-set is the <u>sum of the absolute value of the difference between each observation and the mean, divided by the number of observations</u>.
The mean absolute deviation represents the average by which the values differ from the mean.
In this problem, the data-set is: {101, 115, 124, 125, 173, 165, 170}.
Hence, the mean is:
Then, the mean absolute deviation is:
Hence:
- The <em>mean absolute deviation</em> is of 26.
- It means that the values differ from the mean by an average of 26.

Answer:
i. Curved surface area = 2310
ii. Total surface area = 3696
iii. volume = 12936
Step-by-step explanation:
Perimeter of the circular base = circumference of the circle = 132 cm
circumference of a circle = 2r
132 = 2r
r =
=
r = 66 x
= 3 x 7
= 21
radius = 21 cm
vertical height, h = 28 cm
Thus applying the Pythagoras theorem,
=
+
= +
= 784 + 441
= 1225
l =
l = 35 cm
The slant height is 35 cm.
i. Curved surface area = rl
= x 21 x 35
= 22 x 3 x 35
= 2310
curved surface area of the cone is 2310 .
ii. Total surface area = +
rl
= r(r + l)
= x 21 (21 + 35)
= 22 x 3 x 56
= 3696
The total surface area of the cone is 3696 .
iii. volume of a cone = h
= x
x
x 28
= 12936
The volume of the cone is 12936
