```/*
1. Write a function, favoriteAnimal, that accepts an animal as an argument and console.log's something similar to: "I like <ANIMAL>!"
Ex: favoriteAnimal('cats') should console.log "I like cats!"
*/
function favoriteAnimal(animal) {
console.log('I like ' + animal)
}

favoriteAnimal('octopus')

/*
2. Write a function, double, that takes a number and doubles it
Ex: double(3) should console.log 6
*/
function double(number) {
console.log(number * 2)
}

double(5)

/*
3. Write a function, sum, that takes two numbers and logs their sum
Ex: sum(4, 5) should console.log 9
*/
function sum(x, y) {
console.log(x + y)
}

sum(4, 5)

/*
4. Write a function, areaOfTriangle, that calculates the area of a triangle given its base and height. Hint: the area of a traingle is 1/2 * base * height
Ex: areaOfTriangle(4, 2) should console.log 4
*/
function areaOfTriangle(base, height) {
console.log(base * height * 1/2)
}

areaOfTriangle(4, 10)

/*
5. Write a function, areaOfCircle, that calculates the area of a cirlce given its radius.
Hint: the area of a circle is πr^2.
Another Hint: Use Math.PI to get an approximate value of PI

Ex: areaOfCircle(5) should console.log 78.53981633974483
Challenge: round the logged value to two decimal places
*/

var area = Math.PI * Math.pow(radius, 2)
console.log(Math.round(area))
}

areaOfCircle(5)
