Program to check if tank will overflow, underflow or filled in given time

Given a tank with definite height and radius and the flow of water available to fill the tank. Determine whether the tank will overflow or not in a given amount of time. 
Note: The flow of water will be available in volume per minute.
Examples: 

       --r=5--
   ----------   ^
   |         |  |
   |         |  |
   |         |  h = 10
   |         |  |
   ----------   ^
        
   rate_of_flow = 10

Input : given_time = 10.0
Output : Underflow

Input : given_time = 100.0
Output : Overflow

Approach:
Volume of a cylindrical tank is (22/7) * radius * radius * height. First, find out the amount of time required to completely fill the tank then compare it with the given time. If the given time is greater than required time, it will result in an overflow condition. If the given time is less than the required time then it will result in an underflow condition otherwise the tank is filled.
Below is the implementation of above approach: 

C++

// C++ program to check if Tank will
// overflow or not in given time
#include <bits/stdc++.h>
using namespace std;

// function to calculate the volume of tank
float volume(int radius, int height)
{
    return ((22 / 7) * radius * radius * height);
}

// function to print overflow / filled /
// underflow accordingly
void check_and_print(float required_time,
                       float given_time)
{
    if (required_time < given_time)
        cout << "Overflow";
    else if (required_time > given_time)
        cout << "Underflow";
    else
        cout << "Filled";
}

// driver function
int main()
{
    int radius = 5, // radius of the tank
        height = 10, // height of the tank
        rate_of_flow = 10; // rate of flow of water

    float given_time = 70.0; // time given

    // calculate the required time
    float required_time = volume(radius, height) /
                                    rate_of_flow;

    // printing the result
    check_and_print(required_time, given_time);
    return 0;
}

    {
        if (required_time < given_time)
            System.out.print( "Overflow" );
        else if (required_time > given_time)
            System.out.print( "Underflow" );

        double given_time = 70.0; // time given

        // calculate the required time
        double required_time = volume(radius, height) /
                                    rate_of_flow;

        // printing the result
