Answer 1

Yes, that's because you define variable <x> as `int` which is for whole numbers.

You need to use `double` if you want to have fractional number. When you define <x> as `double` type, then Convert.ToInt32() is not necessary.

double x = ( radius * radius ) * pi;

Answer 2

Ok

Answer 3

Line 6:

Line 18:
Convert calculation result to integer
int x = Convert.ToInt32( ( radius * radius ) * pi );

Line 24:
Add closing curly bracket }

P.S. Add C# in the tags ☝
