find the area of a sector of a circle in rust

To find the area of a sector of a circle in Rust, you can use the following formula:

main.rs
area = (θ/360) * π * r^2

Where θ is the central angle of the sector, r is the radius of the circle and π is the mathematical constant pi (approximately equal to 3.14).

Here's an example Rust function that takes in the central angle and radius of a sector, and returns the area:

main.rs
fn sector_area(angle: f64, radius: f64) -> f64 {
    let pi = std::f64::consts::PI;
    let angle_in_radians = angle * (pi / 180.0); // Convert angle to radians
    let area = (angle_in_radians / (2.0 * pi)) * pi * radius.powi(2);
    area
}

You can use this function in your Rust program to find the area of a sector of a circle. Remember to include the math crate in your Cargo.toml file, since we used the std::f64::consts::PI constant from it in our code.
