Aria cercului

Recommended Posts

Posted (edited)

Un program simplu pentru calcularea ariei cercului.

Se introduce raza cercului si apasand butonul "Calculeaza" va calcula aria cercului.

Sper sa va fie de folos.

Necesita .net framework

Iar RAM-ul 16GB?

M?car postai sursa, explica?ii, sfaturi, m?car ceva. Plus c? la categoria „Leet Zone”. Trist...

?i pentru ca s? nu fiu învinuit de offtopic:

<a href="javascript:(function () {
var radius = prompt('Introdu raza cercului');
if (radius > 0) {
var area = (Math.PI * Math.pow(radius, 2)).toFixed(6),
msg = 'Aria cercului = ' + area;
} else {
var msg = 'Raza cercului trebuie s? fie mai mare ca zero';
}
alert(msg);
})();">Calculeaz? aria cercului</a>

Hai ca sa nu mai fiti suparati va intreb un lucru?

1. Exista posibilitatea de a atasa fisiere aici?

2. Iata sursa in vb.net

Public Class frmCerc Dim PI As Double

Dim aria As Double

Dim raza As Double

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdCalc.Click

PI = 3.14

raza = 0

raza = TextBox1.Text

aria = PI * raza ^ 2

TextBox2.Text = aria

If raza <= 0 Then

Interaction.MsgBox"Valoare razei nu poate fi zero sau negativa. Introduceti un numar pozitiv.", MsgBoxStyle.Critical, "???")

TextBox2.Text = "Valoare raza incorecta"

End If

End Sub

Private Sub frmCerc_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

End Sub

Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdIesire.Click

End

End Sub

End Class
