In this problem you must create functions to solve each criteria. The first criteria is to solve the area of a circle. The function will have the parameter of radius and the function will calculate the area of the circle with the radius and Pi$.$ Then it will return the area of the circle. Return the value, not a print statement. Parameters for the function will be pi and radius.area of a circle $=$ Pi $*$ r$^2$Repeat for the remaining criterias:Total due $=$ money $+($money $*$ tax$)$ : money and tax rate are the parameters for the function. Return total due.Celsius $=($Fahrenheit $-32)*(5/9)$ : Convert Fahrenheit to Celsius temperature where Fahrenheit is the parameter for the function. This function will return the Celsius value.This should be one program with three separate functions. The program will use print statements to print the values returned from the functions.InputPrompt for the input as shown below. Data will be entered from console. You do not need to edit the input data. Rerun your application to test each test case.OutputThe correct answer to each criteria.Test Data $-$ Area of a CircleInputOutput$10314\mathrm{.}166113\mathrm{.}1241809\mathrm{.}56212\mathrm{.}5713\mathrm{.}14$Test Data $-$ TaxesInput $-$ MoneyInput $-$ Tax RateOutput$206\%21\mathrm{.}20544\%56\mathrm{.}16688\%73\mathrm{.}44$ Test Data $-$ TemperatureInputOutput$3208026\mathrm{.}66677322\mathrm{.}7778425\mathrm{.}55556$
