Question
What is the output for the following code? 12345678910#include <stdio.h>#include <math.h> int main() { double r = 5.0, h = 7.0; double v = (pow(r, 2) * h) / 3; printf("%.2lf", v); return 0;}Marks : 1Negative Marks : 0
Solution
The code is written in C language. It calculates the volume of a cone with radius 'r' and height 'h'. The formula for the volume of a cone is (1/3)πr²h.
Here, the radius 'r' is 5.0 and the height 'h' is 7.0. The 'pow' function is used to square the radius.
The 'printf' function is used to print the result, and "%.2lf" is used to print the result up to two decimal places.
However, the code seems to be missing the multiplication by Pi (3.14159) in the volume calculation. The correct formula should be v = (3.14159 * pow(r, 2) * h) / 3;
So, as it stands, the code will not output the correct volume of a cone. It will output the result of (5.0^2 * 7.0) / 3, which equals 58.33.
