The** area** of a circle is the region occupied by the circle. It is the product of pi (π) and the square of the circle’s radius. To do this, we need to create a constant variable `pi`

that will hold our pi value. Then we multiply this value by the square of the radius. We need to use the **Math.pow()**** method** to calculate the squared value of the radius. To do this, we need to import the `scala.math`

library.

pi * Math.pow(radius, 2)

Syntax for finding the area of a circle in Scala

: This is the **pi**`pi`

constant variable.

: This is the given radius of the circle.**radius**

A `float`

value is returned, which is the area of the circle.

// import math package import scala.math._ object Main extends App { // create a constant val PI = 3.14F // create some radii var radius1 = 5 var radius2 = 3.5F var radius3 = 20 var radius4 = 4 // get area of circles var area1 = PI * Math.pow(radius1, 2) var area2 = PI * Math.pow(radius2, 2) var area3 = PI * Math.pow(radius3, 2) var area4 = PI * Math.pow(radius4, 2) // print values println(area1) println(area2) println(area3) println(area4) }

Get the area of a circle in Scala

- Line 2: We import the
`math`

module. - Line 6: We create a
`PI`

value. - Line 9–12: We create some radii.
- Line 15–18: We get the area of some circles.
- Line 21–24: We print the areas to the console.
