Question

设圆半径r=1.5,圆柱高h=3,求圆周长、圆面积、圆球表面积、圆球体积和圆柱体积.用scanf函数输入数据,

Answer 1

#include

#include

#define PI 3.1415

void main()

{

x09float r = 1.5,h = 3;

x09float circ = 2*PI*r;

x09float area = PI*r*r;

x09float surface_area = 4*PI*r*r;

x09float volume1 = 3*PI*r*r*r/4;

x09float volume2 = PI*r*r*h

x09printf("圆的周长为：%.2fn",circ);

x09printf("圆的面积为：%.2fn",area);

x09printf("圆球的表面积为：%.2fn",surface_area);

x09printf("圆球的体积为：%.2fn",volume);

x09printf("圆柱的体积为：%.2fn",volume2);

x09syatem("pause");

}
