Which of the following formulas, when evaluated using rational values for the variables, will result in an irrational number?

 The formula for the area of a circle.

Step-by-step explanation:

1. The formula for calculate the area of a circle is:

Where r is the radius of the circle.

2. By definition, the number π is an irrational number, because it cannot be expressed as a simple fraction. Therefore, if you want to calculate the area of a circle, the result will be an irrational number.

3. Then, the answer is the first option.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

answer: r there any options?
