I think you mean circumference...Area is 
. We have the area so we need to use it to solve for the radius which we will then use in the circumference formula. 
. Divide both sides by pi to get 
. Of course the simplification of the left side gives us 
and r = 4. Now fill that in to the circumference formula, which is 
, to get C
which is a circumference of 
I got confused I add or multiply 30 3 times? Or am i wrong

Answer:
15,267
Step-by-step explanation:
To solve this problem, lets use the exponential growth formula which is:
A = total amount
P = original amount
r = growth rate (decimal)
t = years
<u>Before we plug in the values, don't forget to change 3.5% to its decimal form.</u>
3.5% -> -> 0.035
Lets plug in the values:
The population after 7 years will be 15,267.
Answer:
Step-by-step explanation:
1.
c+9=±8
either c=8-9=-1
c=-8-9=-17
so c=-1,-17
D
2.
8x^2-3=2
8x^2=5
so A
3.
so D
