利用Java计算圆柱体积

计算圆柱的体积

import java.util.Scanner;

public class Yuanzhutiji {
public static void main(String[] args) {
double radius;
double area;
Scanner input = new Scanner(System.in);
System.out.print(“请输入圆柱底面半径：”);
radius = input.nextDouble();
System.out.print(“请输入圆柱的高：”);
double tall = input.nextDouble();
area = Math.PI * radius * radius * tall;
System.out.print("圆柱的体积 = " +area);
}
}
