Program Listing
import kotlin.math.*

fun main() {
    val r = 8.12
    val area = PI * r * r
    val roundedArea = round(area * 100) / 100 // round to 2 decimal places
    
    println("\n\nArea of a Circle in Kotlin\n");
    println("Give radius :  $r\n");
    println("The area of the circle is: $roundedArea")
}
