Problem Solution:

Here, we will read the height, radius from the user. Then we will calculate the surface area and volume of Cone and print the result.

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, volume of Cone

use std::io;

fn main() 
{
    let mut height:f32  =0.0;
    let mut radius:f32   =0.0;
    
    let mut area:f32    =0.0;
    let mut volume:f32  =0.0;
    
    let mut input1 = String::new();
    let mut input2 = String::new();
    
    println!("Enter height: ");
    io::stdin().read_line(&mut input1).expect("Not a valid string");
    height = input1.trim().parse().expect("Not a valid number");
    
    println!("Enter radius: ");
    io::stdin().read_line(&mut input2).expect("Not a valid string");
    radius = input2.trim().parse().expect("Not a valid number");
    
    volume = (1.0 / 3.0) * (3.14) * radius * radius * height;
    area = (3.14) * radius * (radius + (radius * radius + height * height).sqrt());

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

Output:

RUN 1:
Enter height: 
2.5
Enter radius: 
1.2
Volume of Cone    : 3.7680006
Surface area of Cone: 14.970586

RUN 2:
Enter height: 
12.4
Enter radius: 
25.6
Volume of Cone    : 8505.699
Surface area of Cone: 4344.3564

Explanation:

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