Find the lateral area of this cone.
2 answers:
Given:
Radius of the base of the cone = 12 in.
The slant height of the cone = 15 in.
To find:
The lateral surface area of the given cone.
Solution:
The lateral surface area of the cone is:
Where, r is the radius of the base of the cone and h is the slant height of the cone.
Putting , we get
The lateral surface area of the cone is 180π in ² and the missing value for the blank is 180.

Answer:
Step-by-step Explanation:
The 44th percentile, , of the given data can be calculated using the kth formula for percentile given as:
where,
i = the ranking or the position of the percentile = ?
k = the percentile = 44
n = total number of the given data values = 23
Plug in the values into the formula to find "i"
Since "I", 10.56, is not an integer, round the number down, and round it up to the nearest integer, then look for the position each occupy in the ordered data set, and find their average.
Thus,
The data occupying the 10th position on the data set = 28.7
11th = 31.1
