56.52 ÷ pi(3.14) = 18
18 ÷ 2 =9
A = pi(3.14)r^2
A = 3.14 × 9^2
A = 3.14 × 81
A = 254.34in^2

Answer:
(B)1059.265 deer per square mile
Step-by-step explanation:
Population Density in Clinton County = 23 deer per sq. mile.
Area of state of Pennsylvania = 46.055 sq miles
Since the population density of deer in the entire state of Penn. is the same as in Clinton County.
Population Density of deer in Pennsylvania = 23 deer per sq. mile.
Population Density = Number of Deers/Area of the Region
23 = x/46.055
Cross Multiplying
x=23 X 46.055
=1059.265 deer per square mile
There are 1059.265 deer per square mile in Pennsylvania.
r = - 18
multiply both sides by 3 to eliminate the fraction
3 × 6 = - r ⇒ 18 = - r ⇒ r = - 18
