Rust program to calculate the Surface Area and Volume of Sphere

Program/Source Code:

The source code to calculate the surface area, volume of the Cone is given below. The given program is compiled and executed successfully.

// Rust program to calculate the 
// Surface Area and Volume of Sphere

use std::io;

fn main() 
{
    let mut radius:f32   =0.0;
    
    let mut area:f32    =0.0;
    let mut volume:f32  =0.0;
    
    let mut input = String::new();
        
    println!("Enter radius: ");
    io::stdin().read_line(&mut input).expect("Not a valid string");
    radius = input.trim().parse().expect("Not a valid number");
    
    volume = (4.0 / 3.0) * (3.14) * radius* radius* radius;
    area = 4.0 * (3.14) * radius* radius;

    println!("Volume of Sphere 	    : {}", volume);
    println!("Surface area of Sphere: {}", area);
}

Output:

RUN 1:
Enter radius: 
3.5
Volume of Sphere            : 179.50334
Surface area of Sphere: 153.86002

RUN 2:
Enter radius: 
12.3
Volume of Sphere            : 7790.831
Surface area of Sphere: 1900.2025

Explanation:

Here, we read the radius from the user. Then we calculated the surface area, volume of the Sphere and printed the result.
