Answer:
A = 50.24 cm
Step-by-step explanation:
Area formula of a circle:
A = π r²
diameter- r+r
which means that your diameter(8) divided by 2 = 4
r of circle= 4
A= 3.14(4²)
A = 3.14(16)
A = 50.24 cm

Answer:
<h2>The year is 2010.</h2>
Step-by-step explanation:
The population of wolves is given by P(t) = 80(0.98)t.
The study has began in the year of 2000 and will end in 2020.
The difference between 2000 and 2009 is 9 years and the difference between 2009 and 2020 is 11 years.
Hence, the maximum value of t is 11.
The domain is
.
The population will be 80, that is P(t) = 80.
Hence, 0.98t = 1, or, t =
≅1.
In (2009 + 1) = 2010, the population of wolves will be 80.
