Answer:
Option C) 0.2358
Step-by-step explanation:
We are given the following data set:
0.23105, 0.4725, 0.8765, 0.4865, 0.5326, 0.7976
Formula:
where are data points, is the mean and n is the number of observations.
Sum of squares of differences = 0.1122752556 + 0.008765640625 + 0.09633264063 + 0.006340140625 + 0.001123925625 + 0.05358067562 = 0.2784182787
Thus, the standard deviation for given data is
Option C) 0.2358
Answer:
W=16
Step-by-step explanation:
Because 2*16*2= 64 so it would be 64-64 which is 0
Please check the attached picture
To find the total surface area of this cone, we have that the total lateral area is given by the formula:
Where
s is the slant height of the cone, s = 12 inches.
r is the radius of the base of the cone, r = 7 inches.
To that area, we need to add the area of the base of the cone:
That is, this is the area of a circle with this radius. Then, the total surface area is:
Substituting the values in this formula, we have:
Then
Hence, the total area is equal to 417.62 square inches.
