Area of a circle c# project 1

Question

Hey guys. Doing the first code project is frustrating me. I know I need to make radius = Convert.ToDouble(Console.ReadLine), but I don't know what math is needed to solve it. Pi squared , is that * 2? Heck. When Google gives how to find the area of a circle i got snagged so hoping for some assistance. Thanks

Good attempt.
I made a little mistake when I told you **2 = squared, that was for Python -> my bad!

Here is your code tweaked.
I adjusted your "d" parameter as it was incorrect and not being used, so commented out of the program.

Also fixed your "a" parameter

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
const double pi = 3.14;
double r = Convert.ToDouble(Console.ReadLine());
// double d = 2*pi*r;
double a = pi*r*r;
Console.WriteLine(a);

}
}
}

Diameter = 2 * Pi * R
Area Circle = Pi * R **2

**2 -> squared
Pi = 3.14

class Program
{
static void Main(string[] args)
{

double a = pi*r**2;
Console.WriteLine(a);

}
}
