Answer:
(d) if (radius > 0) System.out.println(radius * radius * 3.14159);
Explanation:
Given
Code segment (a) to (d)
Required
Which is correct
Code segment (a): radius <=0
This means that radius is 0 or less, i.e. 0 or negative
Code segment (b): radius !=0
This means that radius is not equal to 0 i.e. it could be positive or negative but definitely not 0
Code segment (c): radius >=0
This means that radius is 0 or greater, i.e. 0 or positive
Code segment (d): radius >0
This means that radius is greater than 0 i.e. positive
<em>Hence, (d) is correct</em>
