Question

I need help pls

Answer 1

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 radius;
double area;
//your code goes here
radius = Convert.ToDouble(Console.ReadLine());

Console.WriteLine(pi*radius*radius);
}
}
}
Hope, this will help you.

I appreciate your effort for helping everyone. But, we need to see what they have done so far.

Answer 3

Show your attempt. Where is your code?

Answer 4

Alice Petey , giving ready answers to the task prevents learners from learning syntaxes & understanding logic & concepts behind the given task.

Yes, absolutely agree with you visph.

Answer 5

circle area = PI * radius * radius

Answer 6

I just give the circle area formula... I guess that's not the point of the task, as it is a well known formula, even by childs... I rather believe that the point of the task is to apply this formula in a program ^^

Answer 7

Oh thank you im learning c# but sometimes is very confused

Answer 8

that's why I was trying to help by giving you the mathematic formula, to let you concentrate on code rather on loosing time to get the good maths ;P

Answer 9

visph

Exactly, my point was same as yours. It's a well know formula even with just one Google search we can find it easily.

We all stuck at some point while learning. It's just that when we do some research and try to solve with small steps (we learn more) :) 🤷

Answer 10

Shivani 📚✍ [Exams] sure, that's why I believe that we must concentrate on coding skills rather on maths skills when learning programation languages ;)

Answer 11

Alice Petey it would help to solve, but it wouldn't help to learn ^^

Answer 12

Try this =>
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 radius;
//your code goes here
radius = Convert.ToDouble(Console.ReadLine());
double area = pi * radius * radius;
Console.WriteLine(area);
}
}
}

Answer 13

use a circle area equation and mix that with the some input.

Answer 14

Jajaja thank you

Answer 15

please don't upload code.

Answer 16

I don't think you are talking about the syntax.
So Area of circle = Pi*radius*radius.
Pi=22/7;
