Answer:
d. if (radius > 0) System.out.println(radius * radius * 3.14159);
Explanation:
The positive values are those values that are greater than 0(zero).0 is considered to be nonnegative number it is neither positive nor negative and for a zero radius the area will be 0.As we know the are of the circle is π*radius*radius, and π is 3.14159.So the correct answer matching to this condition is option d.
Which checks if the radius is greater than 0 then find the radius and print it.

<h3>What is a function?</h3>
A function refers to a named portion of a block of executable code that is written to perform a specific task, which is usually a single, related action.
Thus, a function comprises a group of related statements (block of code) that would only run and returns a data when it is called.
In Computer programming, if an error occurs within a program, each of the numeric functions would return a <u>null value</u>.
