Hello,
The formula for finding the circumference of a circle is 

 where r is the radius. SO we can plug 4 in for r in this formula because 4 is the radius:

. We are told to use 3.14 for 

 so we get 

. Therefore, the circumference is 25.12 meters.

To answer the question above we first need to know how much is the interest per year. In equation, 3% of $2500 is 75. 75 per year in 4 years is 300. So add $300 to the principal amount, the money after 4 years would be $2800.
        
             
        
        
        
Answer:
x = -9
Explanation:
(3x + 9)^5 = 32x^5
(3 (x + 3))^5 = 32x^5
3^5 (x + 3)^5 = 32x^5
243(x + 3)^5 = 32x^5
243(x + 3)^5 - 32x^5 = 0
x = -9

Answer:
   multiply by 3 and divide by 2 to get 6x -y = 12.
Step-by-step explanation:
A standard form equation has mutually prime integers for coefficients, and the leading one is positive. We can get that here by multiplying by 3 (to eliminate the denominator) and dividing by 2 (to remove that common factor). The result is ...
   4(3/2)x -(2/3)(3/2)y = 8(3/2)
   6x -y = 12
