find the area of a circle in rust

To find the area of a circle in Rust, we need to use the following formula:

main.rs
Area = π * (radius)^2

Here's the Rust code snippet to calculate the area of a circle:

main.rs
use std::f64::consts::PI;

fn main() {
    let radius = 5.0;
    let area = PI * radius.powi(2);
    println!("The area of the circle is {}", area);
}

8 lines

In the code above, we first import the PI constant from the f64 module which represents the value of Pi (π) to double precision.

We then define the radius of the circle to be 5.0 and calculate the area of the circle using the formula PI * radius.powi(2).

Finally, we print out the result using the println! macro. This will output The area of the circle is 78.53981633974483.
