The area would be approximately 153.94.
The area of a circle is pie multiplied by r^2. 
So you have the radius, which is r. Plug in r. Technically you have two numbers because pie equals approximately 3.14. 
A=3.14(7)^2 
        
             
        
        
        
Answer:
(x-5)² + y² = 4
Step-by-step explanation:
formula of circle: (x-h)² + (y-k)² = r²  where (h,k) is coordinate of center and r is radius
center: (5 , 0)    r = 2
Equation: (x-5)² + y² = 4
 
        
             
        
        
        
Answer:
Step-by-step explanation:
1/3x > -4
cross multiply
1>-4 × 3x
1>-12x
solve for x
x = -1/12

Answer:
475
Step-by-step explanation:
Is means equals.  We need to change 8% to a decimal.  8% = .08.  Of means multiply.  X is the unknown number.
38 = .08 * x
Divide each side by .08
38/.08 = .08x /.08
475 = x
The unknown number is 475
