Write the contents of an XHTML file cake. html. This file should contain JavaScript messages that prompts the user to enter the size of a cake (the diameter) and the price of a cake. Using the input that the user enters, calculate the price per square inch. •For constant π, use Math. PI.
•Calculate the radius using the following formula:
radius = diameter / 2
•Calculate the area (consider the cake to be a circular or a round cake), using the following formula:
area = πr2
•You can calculate the radius squared in JavaScript with the following formula:
radius * radius
•Ensure that you write XHTML comments near the top of the file that includes the file name, learner’s name, the date, and the assignment name (Task 4 for Computer Science-1A). All tags should follow the XHTML standard.

Working on this program in python 3.7: a year in the modern gregorian calendar consists of 365 days. in reality, the earth takes longer to rotate around the sun. to account for the difference in time, every 4 years, a leap year takes place. a leap year is when a year has 366 days: an extra day, february 29th. the requirements for a given year to be a leap year are: 1) the year must be divisible by 42) if the year is a century year (1700, 1800, the year must be evenly divisible by 400some example leap years are 1600, 1712, and 2016.write a program that takes in a year and determines whether that year is a leap year.ex: if the input is 1712, the output is: 1712 is a leap year. ex: if the input is 1913, the output is: 1913 is not a leap year. your program must define and call the function isleapyear(useryear). the function should return true if the input year is a leap year and false otherwise.
