Question

How to calculate surface area of cone in Rust

Answer 1

fn main() {
    let r:f32 = 5.0; // radius
    let h:f32 = 13.0; // height
    
    let pi:f32 = std::f32::consts::PI;

    let surface_area:f32 = pi * r * (r + ((h * h) + (r * r)).sqrt());

    println!("Surface Area of Cone = {}", surface_area);
}




/*
run:
   
Surface Area of Cone = 297.32645
   
*/
