导入math模块，创建接收输入并进行分割

import math

r = input()
list_r = r.split(' ')

定义两个函数ball_volume和ball_area

def ball_volume(radius):
    v = round(4 / 3 * math.pi * radius ** 3, 3)
    return v


def ball_area(radius):
    s = round(4 * math.pi * radius ** 2, 3)
    return s

创建程序主入口进行函数调用

if __name__ == "__main__":
    for i in list_r:
        print("%.3f %.3f" % (ball_volume(int(i)), ball_area(int(i))))
