Answer:

Step-by-step explanation:

Initial number of Condors = 22

New number of Condors = 405

Use percentage increase formula to find the percentage increase in Condor's population in 2012;

Percentage increase = \frac{(New - Initial)}{Initial} * 100

Next, plug in the numbers into the formula;

Percentage increase = \frac{(405-22)}{22} *100\\ \\ =\frac{383}{22} *100\\ \\ =1740.909091

=Therefore, they increase by 1741% to the nearest whole percent.

Answer:

1.) 471.24

2.) 1231.5

3.) 113.1

Step-by-step explanation: A = pi x r^2 + pi x r x ^2

1.) a = 3.14 x (5)^2 + 3.14 x 5 x ^2

a = 3.14 x 25 + 3.14 x 5 x 25

a = 78.54 + 392.70

a ≈ 471.24

2.) A = 3.14 (7)^2 + 3.14 x (7) x ^2

a = 3.14 x 49 + 3.14 x 7 x 49

a = 153.93 + 1077.57

a ≈ 1231.5

3.) a = 3.14 (3)^2 + 3.14 x 3 x ^2

a = 3.14 x 9 + 3.14 x 3 x 9

a = 28.27 + 84.82

a ≈ 113.1
