Determine the curved surface area of the big cone
The volume of a cone is:
For the big cone:
Where
R = radius of the big cone and H = height of the big cone
For the small cone:
Where
r = radius of the small cone and H = height of the small cone
Because both cones are similar, then:
and
Substitute values for Vbig and Vsmall
Recall that:
So, we have:
Take cube roots of both sides
![\sqrt[3]{\frac{1715}{1080}} = \frac{R}{r}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B1715%7D%7B1080%7D%7D%20%3D%20%5Cfrac%7BR%7D%7Br%7D)
Factorize
![\sqrt[3]{\frac{343*5}{216*5}} = \frac{R}{r}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B343%2A5%7D%7B216%2A5%7D%7D%20%3D%20%5Cfrac%7BR%7D%7Br%7D)
![\sqrt[3]{\frac{343}{216}} = \frac{R}{r}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B343%7D%7B216%7D%7D%20%3D%20%5Cfrac%7BR%7D%7Br%7D)
The curved surface area is calculated as:
Where
For the big cone:
For the small cone
Because both cones are similar, then:
and
This gives:
Recall that:
So, we have:
Make 
the subject
Substitute values for 
and 
<em>Hence, the curved surface area of the big cone is 1143.33cm^2</em>
Answer:
#section 1
def maxTemp(filename):
import pathlib
f = pathlib.Path(filename)
f.exists()
if f.exists():
f = open(filename, "r")
#section 2
next(f)
res = [int(sub.split(',')[1]) for sub in f]
maxdata = (res[0])
for i in range(len(res)-1):
if maxdata < res[i]:
maxdata = res[i]
index = res.index(maxdata)
f.close()
#section 3
li = []
a = open(filename, "r")
for line in a:
line = line.strip()
li.append(line)
a.close()
return (li[index+1])
else:
return -1
print(maxTemp("new.csv"))
Explanation:
#section 1:
The function maxTemp is defined. We import pathlib in other to check if the file exists, if it does we carry on with opening the file and if it doesn't the program returns -1.
#section 2:
We start splitting the sub-lists from the second line i.e <em>next(f)</em>. For each line we take the second index element and convert it to an integer.
<em>res = [int(sub.split(',')[1]) for sub in f]
</em>
The maximum number is gotten by using the if statement to compare all elements in the list. The index of the maximum item in the list is collected.
the file is then closed.
#section 3 :
The file is re-opened and all the lines are striped and passed into a new list and the index recovered from section 2, is used to get the day with the highest temperature and the line is returned.

Answer:
"Case-Based Reasoning" is the answer for the above question.
Explanation:
- Case-Based Reasoning is a process of decision-making theory in which the new problems were solved based on the previously solved problem.
- It is used in artificial intelligence and robots. This helps to make any AI and robots to do the work and take decisions on its own.
- The theory is used to make any computer that behaves like humans. It can take decisions like a human.
- The above question asked about the method by which the new problem is solved on behalf of the old problem. Hence the answer is "Case-Based Reasoning".
