Answer:
The answer is 4143. 36 but I don't know why there are fractions
Step-by-step explanation:
Biggest area for smallest perimiter is a circle
she has perimiter aka circumference=2pir
72=2pir
divide both sides by 2
36=pir
divid both sides by pi
11.4592=r
radius=11.4 feet
circle is biggest area
Answer:
Step-by-step explanation:
Let us assume that if possible in the group of 101, each had a different number of friends. Then the no of friends 101 persons have 0,1,2,....100 only since number of friends are integers and non negative.
Say P has 100 friends then P has all other persons as friends. In this case, there cannot be any one who has 0 friend. So a contradiction. Hence proved
Part ii: EVen if instead of 101, say n people are there same proof follows as
if different number of friends then they would be 0,1,2...n-1
If one person has n-1 friends then there cannot be any one who does not have any friend.
Thus same proof follows.
