- Write a function called
`squareNumber`

that will take one argument (a number), square that number, and return the result. It should also log a string like "The result of squaring the number 3 is 9." - Write a function called
`halfNumber`

that will take one argument (a number), divide it by 2, and return the result. It should also log a string like "Half of 5 is 2.5.". - Write a function called
`percentOf`

that will take two numbers, figure out what percent the first number represents of the second number, and return the result. It should also log a string like "2 is 50% of 4." - Write a function called
`areaOfCircle`

that will take one argument (the radius), calculate the area based on that, and return the result. It should also log a string like "The area for a circle with radius 2 is 12.566370614359172."- Bonus: Round the result so there are only two digits after the decimal.

- Write a function that will take one argument (a number) and perform the following operations, using the functions
you wrote earlier1:
- Take half of the number and store the result.
- Square the result of #1 and store that result.
- Calculate the area of a circle with the result of #2 as the radius.
- Calculate what percentage that area is of the squared result (#3).
