How do I make a program to take input and tell the area of a circle in c#?

Question

When I was learning c# I saw that in module 1 there was a coding problem. I had to take input of a radius and find the area of a circle but I cannot solve it. Can anyone help me solve it?

This will help you if you did not understand what I said.

Answer 2

You need to create a double data type variable called "area", a double data type variable called radius for the user to input and a constant with a double data type called "pi". Assign the value 3.14 to pi.

Do "area = pi * radius * radius;"
Console.WriteLine(area)

Formula for area of a circle - Area = pi(3.14) x radius^2

(Console.ReadLine is used to take input from the user.)

(Console.WriteLine prints the value of the variable.)
