Answer:
200.86
Step-by-step explanation:
Using the formulas:
A=πr2
C=2πr
Solving for A:
A=C2
4π=50.242
4·π≈200.85812

Answer:
A) allows the population effect on log earnings of being married to depend on gender
Step-by-step explanation:
The regression equation of a dependent variable based on two or more independent variables is of the form:

Here,
<em>Y</em> = dependent variable
 and
 and  = independent variables
 = independent variables
 = interaction term
 = interaction term
 = regression coefficients.
 = regression coefficients.
If there is a significant interaction effect present then this implies that the effect of one independent variable ( or
 or ) on the dependent variable (<em>Y</em>) differs every time with different value of the other independent variable  (
 ) on the dependent variable (<em>Y</em>) differs every time with different value of the other independent variable  ( or
 or ) .
 ) .
The provided regression equation is:
 
 = dependent variable
 = dependent variable
 and
 and  = independent variables
 = independent variables
In this case the interaction term is defined as follows:
The effect of being married on log earnings is dependent on different values of the variables  , i.e. the gender of the
, i.e. the gender of the  person.
person.
Thus, the correct option is (A).
 
        
             
        
        
        
Answer:
Initial Amount=1
Decay Factor=0.99987
Decay Rate=0.013%
Step-by-step explanation:
If P = 0.99987ᵃ
I. Initial amount 
The initial amount is when a=0
P = 0.99987⁰ = 1
The Pressure at Sea Level=1
II. Decay factor 
This is like the decay constant. From the model, P = 0.99987ᵃ, the decay constant/factor is 0.99987.
III. Decay Rate = 1-0.99987 = 0.00013
Expressed in Percentage = 0.013%
