这里给出的是一个正圆柱体,其高度增加了给定的百分比,但半径保持不变。任务是找出圆柱体体积增加的百分比。
例子:
Input: x = 10
Output: 10%
Input: x = 18.5
Output: 18.5%
方法:
- 让,圆柱的半径 = r
- 圆柱体高度 = h
- 给定百分比增加 = x%
- 所以,旧体积 = π*r^2*h
- 新高度 = h + hx/100
- 新体积 = π*r^2*(h + hx/100)
- 所以,体积增加 = πr^2*(hx/100)
- 所以体积增加百分比 = (πr^2*(hx/100))/(πr^2*(hx/100))*100 = x
C++
// C++ program to find percentage increase
// in the cylinder if the height
// is increased by given percentage
// but radius remains constant
#include
using namespace std;
void newvol(double x)
{
cout << "percentage increase "
<< "in the volume of the cylinder is "
<< x << "%" << endl;
}
// Driver code
int main()
{
double x = 10;
newvol(x);
return 0;
}
Java

import java.io.*;
class GFG

static void newvol(double x)
{
System.out.print( "percentage increase "
+ "in the volume of the cylinder is "
+ x + "%" );
}
// Driver code
public static void main (String[] args)
{
double x = 10;
newvol(x);
}
}
