Answer:
A≈118.2
Step-by-step explanation:
r= Radius= 3.5
l= Slant height= 7.25
A= πrl+πr2= π·3.5·7.25+π·3.52≈118.20242

Answer:
1/3
Step-by-step explanation:
Let A be the event that you grab the fair coin and B be the event that you toss a tail.
P(A) is the probability that you grab the fair coin, which is 1/3
P(B) is the probability that you toss a tail, which is 1/2
P(B|A) is the probability that you toss a tail, given that you grab a fair coin, which is 1/2
P(A|B) is the probability that you grab the fair coin, given that you toss a tail, which we are looking for.
Using Bayes probability theorem we have:

I think this is right. The answer is 12.
24 times 9 equals 216, which is the area of the room floor.
Then I did 6 times 3 equals 18.
Then I divided 216 by 18 to get 12.
