Question

Scrieti cate un algoritm care calculeaza si afiseaza:
a) Volumul unui trunchi de con V= (pi*h)/3 Conditii : R1, R2,h >0
b) Aria unui paralelogram A=d1*d2*sin a
Conditii: d1,d2>0 ; a E (0,pi/2)
c) Aria totala a unui cilindru circular drept A=2*pi*R*(R+G)
Conditii R,G>0
d) Aria unui trapez oarecare A=(b1+b2)*h/2
Conditii: b1,b2,h>0

Answer 1

1.
int v,h,r1,r2;
float pi=3,14
cin >> h;
if(r1,r2,h>0){
v= (pi*h)/3;
cout << v;}
2.
int a,d1,d2,sina;
cin >> sina;
cin >> d1;
cin >> d2;
if(d1,d2 > 0){
a=d1*d2*sina;
cout << a;
3.int a,r,g;
float pi=3,14;
cin >> r;
cin >> g;
if(r,g > 0){
a=2*pi*r(r+g)
cout << a;
4.int a,b1,b2,h
if(b1,b2,h>0){
a=(b1+b2)*h/2
cout << a;
