// 1. Attach this file geometry.js to the index.html file
// 2. Create a function that calculates the area of a rectangle. // The function should accept the width and height as arguments // and return the area of that rectangle. // The area of a rectangle is the width * height
function areaOfRectangle (width,height) { var area = width * height return area }
// 3. Create a function that calculates the volume of a rectangular prism. // The function should accept the width, height and length as arguments // and return the volume of that rectangular prism. // The volume of a rectangular prism is the width * height * length
function volumeOfRectanglarprism (width, height, length) { var volume = width * height * length return volume }
// 4. Create a function that calculates the area of a circle. // The function should accept the radius of the circle as an argument // and return the area of that circle. // The area of a circle is the value of π * radius^2
function areaOfCircle (radius) { var areaofcircle = π * radius^2 return areaofcircle }
// 5. Create a function that calculates the volume of a sphere. // The function should accept the radius of the sphere as an argument // and return the volume. // The volume of a circle is: 4/3 * π * radius^3
function volumeOfCircle (radius) { var volumeofcircle = 4/3 * π * radius^3 return volumeofcircle }

54,971 PointsYour console.log statements need to include parentheses
console.log(areaOfRectangle (5,22));
instead of
console.log areaOfRectangle (5,22);

54,971 PointsYou defined it as areaOfCircle with an uppercase O. Same with volumeOfCircle.
I also ended up substituting 3.14 for π.
