hi can someone help me to make a calculator as required?

Create class Calculator. This class must contain the following features:

constant PI

constructor that accepts two integers, operand1 and operand2

method for writing values and operand2 operand1

methods for calculating the four operations - addition, subtraction, division and multiplication that will return the result of operand1 and operand2 operation on values

static methods for these operations, which accepts parameters as operands

method that calculates the surface area of the circle diameter circle operand1.

Create a console application that instantiates object of class Calculator, call all the methods and write the result of calculation.

pls thanks

sorry for my bad english
