The answer is letter d) 3
1.
In line with the test each person who came into interaction
with the infected person will become infected also. With this information, the
calculation would be: 9 people each day for 7days would be equivalent to 9 x 7
which equals 63 people.
2.
Here were 7 other people in the experiment if patient
zero is left out. If each person intermingled with 6 different people every day
in 7 days then the calculation would be: 7 people infected x 6 new people = 42
infected people each day
42 new people every day x 7 days = 294
infected persons.
C=2πr
r=C/(2π), now the surface area is:
A=4πr^2, using r found above we have:
A=4πC^2/(4π^2)
A=C^2/π, we are given that C=28 so:
A=28^2/π in^2
A=784/π in^2
A≈250 in^2 (to nearest square inch)
Answer:
