Answer: 7/19
Option A: All real numbers is the right answer
Step-by-step explanation:
First of all, let us define domain
Domain is the set of all inputs to a function on which the function is defined
So
Given function is:

The given function will not be undefined for any value of x as there is no denominator which will make the function approach infinity
Hence,
Option A: All real numbers is the right answer

Step-by-step explanation:
Given: Radius of Circle A= 4
Radius of Circle B= 5
Radius of circle C= 6
Radius of circle D= 7
Now, finding circumference and area of all the circle.
We know, circumference of circle= 
Area of circle= 
Where, r= radius of circle and π = 3.14
First, solving for figure A
Circumference= 
Area= 
Solving for Figure B
Circumference= 
Area= 
Solving for Figure C
Circumference= 
Area= 
Solving for Figure D
Circumference= 
Area= 
∴ 1. Answer is Figure B.
2. Answer is figure C.
3. Answer is Figure D
4. Answer is Figure C.
