Numbers in C# Step 5

Hi! Whilst doing Numbers in C#, step 5.

The question is to calculate the area of a circle.

i’ve got the following code: `double radius=2.15; double pi = Math.PI; double oppervlakte = pi * (radius * radius); Console.WriteLine(“De oppervlakte van de circel is: {0}”, oppervlakte);

when i submit this code, it gives an invalid value. Because the IDE on the web gives me as answer: De oppervlakte van de circel is: 14.5220120412188

Whilst, i submit this code in my VStudio it gives the answer: De oppervlakte van de circel is: 19,6349540849362

`

No worries. Thanks for confirming @turbobaap!

I’m running that code in Visual Studio and I’m getting “De oppervlakte van de circel is: 14.5220120412188”

As @shrah said, I only get the 19.63… result if radius is 2.5. Can you try again to run that code in Visual Studio?
