设有以下宏定义: #define S(x) x/x int a=4,b=3,area; 执行语句area=S(a+b);后,area的值为()

下面代码的执行结果是。 def area(r, pi = 3.14159): return pi * r * r print(area(3.14, 4))

a=3; b=4; c=5; >>s=(a+b+c)/2; >>area=sqrt(s*(s-a)*(s-b)*(s-c)) 以上运行结果为 area = （ ） A: 3 B: 4 C: 5 D: 6

下面代码的执行结果是 >>> def area(r, pi = 3.14159): return pi * r *r >>> area(pi = 3.14, r = 4)

写出以下程序的输出结果为______。#define S（r） r*r void main（）{int a=4,b=6； int area；area=S（a+b）；printf（“area=%d”,area）； } A: 100 B: 28 C: 24 D: 34

4 The people had a hard life even_______.So they were_____when the area was hit by the terrible earthquake.

The leaf area index can be defined as the A: A, green leaf area/yellow leaf area B: B, land area/leaf area C: C. Total green leaf area/land area D: D, yellow leaf area/green leaf area

According to the situation and the route, which activity area is the reading area next to? A: Intelligence area B: Construction area C: Performance area D: Role-play area

def area(r, pi=3.14):return round(pi*r*r,2),the value of area(pi=3.14, r=4) is A: 50.24 B: 39.44 C: 50 D: 39

下面代码的执行结果是( )。def area(r, pi = 3.14159): return pi * r * rprint(area(3.14, 4)) A: 39.4384 B: 50.24 C: 无输出 D: 出错
