5. 用C赋值语句表示以下计算式：

1）Area=?r2+2?rh

2m1m2?g2）Torque=

m1?m2

3）Side=a2?b2?2abcos(x)

(velocity)24）Energy=mass[acceleration×height+]

2【参考答案】

1）Area=PI*r*r+2*PI*r*h

2）Torque=（(2*m1*m2)/(m1+m2)）*g 3）Side=sqrt(a*a+b*b-2*a*b*cos(x))

4）Energy=mass(acceleration*height+velocity*velocity/2) 转换成程序： #include \#define PI 3.1415926 void main() { float r,h,Area; printf(\ scanf(\ pirntf(\ scanf(\ Area=PI*r*r+2*PI*r*h; printf(\} 2）

#include \#define g 9.8 void main()

{ float m1,m2,Torque; printf(\
