# Program to check if water tank overflows when n solid balls are dipped in the water tank in C++

Given with the radius and height of cylindrical water tank, ‘n’ number of spherical solid balls with the radius and the volume of water in the tank and the task is to check whether the tank will overflow or not when balls are dipped in the tank.

## Formula to calculate the volume

**Cylinder**

3.14 * r * r * h

Where, r is radius of tank and h is the height of the tank

**Sphere**

(4/3) * 3.14 * R * R * R

Where, R is radius of sphere ball

**Input**

tank_height = 5 tank_radius = 2 water_volume = 10 capacity = 10 ball_radius = 2

**Output**

It will overflow

## Approach used below is as follows

Input the given dimensions like radius of tank, height of tank, number of balls to be dipped and radius of shere

Calculate the capacity (volume) of a tank by applying the formula

Calculate the volume of a sphere by applying its formula

Calculate the volume of a water as the volume will increase whenever the ball is dipped into a water tank.

Calculate the total volume by adding the volume of water and volume of sphere

Check the condition to state whether the tank will overflow or not

If the total volume is greater than capacity than tank will overflow

If the total volume is lesser than capacity than tank will not overflow

## Algorithm

Step 1→ declare function to check whether tank will overflow or not void overflow(int H, int r, int h, int N, int R) declare float tank_cap = 3.14 * r * r * H declare float water_vol = 3.14 * r * r * h declare float balls_vol = N * (4 / 3) * 3.14 * R * R * R declare float vol = water_vol + balls_vol IF (vol > tank_cap) Print it will overflow End Else Print No it will not overflow End Step 2→ In main() Declare int tank_height = 5, tank_radius = 2, water_volume = 10, capacity = 10, ball_radius = 2 call overflow(tank_height, tank_radius, water_volume, capacity, ball_radius)

## Example

#include <bits/stdc++.h> using namespace std; //check whether tank will overflow or not void overflow(int H, int r, int h, int N, int R){ float tank_cap = 3.14 * r * r * H; float water_vol = 3.14 * r * r * h; float balls_vol = N * (4 / 3) * 3.14 * R * R * R; float vol = water_vol + balls_vol; if (vol > tank_cap){ cout<<"it will overflow"; } else{ cout<<"No it will not overflow"; } } int main(){ int tank_height = 5, tank_radius = 2, water_volume = 10, capacity = 10, ball_radius = 2; overflow(tank_height, tank_radius, water_volume, capacity, ball_radius); return 0; }

## Output

If run the above code it will generate the following output −

it will overflow
