Area of a Circle

Adapted by Neilor Tonin, URI  Brazil
Timelimit: 1
The area of the circle is defined as A = π . R2, having π as 3.14159.
Calculate the area using the formula given in the problem description.

Input

Read the variable R (double precision), that is the radius of the circle.

Output

Print the variable A, rounded to four decimal digits.
Sample InputsSample Outputs
2.00A=12.5664
100.64A=31819.3103
150.00A=70685.7750
Solution:

#include<stdio.h>
int main(){
    double c;
    double pi=3.14159;
    scanf("%lf",&c);
    printf("A=%.4lf\n",pi*c*c);
    return 0;
}

    where is my problem.

    #include

    int main() {
    double A,R;
    double pi=3.14159;
    scanf("%lf",&A);
    R=pi*A*A;
    printf("%.4lf",R);

    return 0;
    }

      Vai problem ta valo kore poren.
      Apni ultakaj korcen.

      R = pi*A*A-er jaygay A = pi*R*R bosan.

URI Online Judge | 1041 Coordinates of a Point (Solution)

Image
Problem Link: https://www.urionlinejudge.com.br/judge/en/problems/view/1041 URI Online Judge | 1041 Coordinates of a Point Adapted by Neilor Tonin, URI   Brazil Timelimit: 1 Write an algorithm that reads two floating values (x and y), which should represent the coordinates of a point in a plane. Next, determine which quadrant the point belongs, or if you are over one of the Cartesian axes or the origin (x = y = 0). If the point is at the origin, write the message "Origem". If the point is over X axis write "Eixo X", else if the point is over Y axis write "Eixo Y". Input The input contains the coordinates of a point. Output The output should display the quadrant in which the point is. Sample Input Sample Output 4.5 -2.2 Q4 0.1 0.1 Q1 0.0 0.0 Origem Solution: #include <stdio.h> int main() {      double x, y;      scanf ( "%lf %lf" , &x, &y);     ...

Problem Link: https://www.urionlinejudge.com.br/judge/en/problems/view/1036 URI Online Judge | 1036 Bhaskara's Formula Adapted by Neilor Tonin, URI   Brazil Timelimit: 1 Read 3 floating-point numbers. After, print the roots of bhaskara’s formula. If was impossible to calculate the roots because a division by zero or a square root of a negative number, presents the message  “Impossivel calcular” . Input Read 3 floating-point numbers A, B and C. Output Print the result with 5 digits after the decimal point or the message if it is impossible to calculate. Sample Inputs Sample Outputs 10.0 20.1 5.1 R1 = -0.29788 R2 = -1.71212 0.0 20.0 5.0 Impossivel calcular 10.3 203.0 5.0 R1 = -0.02466 R2 = -19.68408 10.0 3.0 5.0 Impossivel calcular Solution: #include<stdio.h> #include<math.h> int main() {      double a,b,c,r1,r2,del;      scanf ( "%lf %lf %lf" ,&a,&b,&c);...

Problem Link: https://www.urionlinejudge.com.br/judge/en/problems/view/1043 URI Online Judge | 1043 Triangle Adapted by Neilor Tonin, URI   Brazil Timelimit: 1 Read three point floating values (A, B and C) and verify if is possible to make a triangle with them. If it is possible, calculate the perimeter of the triangle and print the message: Perimetro = XX.X If it is not possible, calculate the area of the trapezium which basis A and B and C as height, and print the message: Area = XX.X Input The input file has tree floating point numbers. Output Print the result with one digit after the decimal point. Sample Input Sample Output 6.0 4.0 2.0 Area = 10.0 6.0 4.0 2.1 Perimetro = 12.1 Solution: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 #include <stdio.h> int main() {      double a,b,c;      scanf ( "%lf %lf %lf" ,&a,&b,&c...
