Which of the following is the Java equivalent of the following mathematical expression?
C = 2$\pi$ . radius
A) c = 2 * Math.PI * radius * 2;
B) c = 2 * Math.PI * Math.pow(2, radius);
C) c = 2 * Math.PI * Math.pow(radius, 2);
D) c = 2 * Math.PI * radius;

Question

Quizplus · Accepted Answer

The provided mathematical expression is for calculating the circumference of a circle with radius "radius". In Java, the value of PI is stored in the "Math.PI" constant. The expression "2 * Math.PI * radius" calculates the circumference of the circle with given radius. Therefore, option D is the correct Java equivalent of the given mathematical expression.

Option A multiplies the radius by 2, which is not necessary as the "2" is already included in the expression.

Option B raises 2 to the power of the radius, which is not mathematically correct for finding the circumference of a circle.

Option C correctly calculates the area of the circle, but not the circumference.
