Answer:
<h2>radius = 9.77 yards</h2>Step-by-step explanation:
Since the pool is circular
Area of a circle = πr²
where
r is the radius
From the question
Area = 300 square yards
To find the radius substitute the value of the area into the above formula and solve for the radius
That's
300 = πr²
Divide both sides by π
We have
Find the square root of both sides
That's
r = 9.7720502
We have the final answer as
<h3>radius = 9.77 yards</h3>Hope this helps you
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.
