To make it easier, aprox pi=3.14
area=pir^2
36=area
36=pir^2
divide both sides by pi
36/pi=r^2
36/3.14=r^2
11.464=r^2
square root both sides
3.39=r
circumfernce=2pir
r=3.39
circumfrence=2pi times 3.39
circumference=pi times 6.78
circumference=3.14 times 6.78
circumfernce=21.29
answer is
circumference=21.29 in
You have zero terms in that equation. A term is when a number is connected to a variable. You have no variables.

Not enough Information. I could say 50 and it would work. I could say 68 and it would work. Any even number thats under 80 but higher than what you think her eldest son is.
You just solve it like a normal multiplication problem and then start putting the decimal begin the answer and place it 3 numbers forward
Answer:
A) ≈22.4 concert attendees might have left early.
B) 605 attendees might leave early.
Step-by-step explanation:
A) 11/100, or 11%, of the sample left early.
11% of all the concert attendees is (11/100) × 2040 ≅ 22.4
attendees who might have left early.
B) 11% of the total attendance is 11% × 5500 = 605 attendees who might
leave early.
