Determina la cilindrada total Vt en un motor de 4 cilindres de 83,6 mm de diàmetre per 91 mm de cursa.
insens350 [35]

Answer:

La cilindrada total del motor es de 1997,025 centímetros cúbicos.

Explanation:

Para determinar la cilindrada total Vt en un motor de 4 cilindros de 83,6 mm de diámetro por 91 mm de carrera se debe realizar el siguiente cálculo, sabiendo que para calcular la cilindrada de un motor se debe utilizar la fórmula ((Pi x Diámetro^2)/4) x Carrera x Número de cilindros = X:

((3.14 x 83.6^2)/4) x 91 x 4 = X

((3.14 x 6,988.96)/4) x 364 = X

(21,945.3344 / 4) x 364 = X

5,486.3336 x 364 = X

1,997,025.4304 = X

1 milímetro cúbico = 0.001 centímetro cúbico

1,997,025.4304 milímetros cúbicos = 1997.0254304000005 centímetros cúbicos

Por lo tanto, la cilindrada total del motor es de 1997,025 centímetros cúbicos.

Using language c, find the nth Fibonacci, knowing that nth Fibonacci is calculated by the following formula: - If n = 1 Or n = 2
Nina [5.8K]

Answer:

#include <stdio.h>

int fib(int n) {

 if (n <= 0) {

   return 0;

 }

 if (n <= 2) {

   return 1;

 }

 return fib(n-1) + fib(n-2);

}

int main(void) {

 for(int nr=0; nr<=20; nr++)

   printf("Fibonacci %d is %d\n", nr, fib(nr) );

 return 0;

}

Explanation:

The code is a literal translation of the definition using a recursive function.

The recursive function is not per se a very efficient one.
