Here's my solution!

I definitely did this in a round about way and forgot to put returns.

// 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 area(width, height){ area = width * height; } area(5, 22); console.log(The area of the rectangle is ${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 volume(width, height, length) { volume = width * height * length; } volume(4.5, 12.5, 17.4); console.log(The volume of the rectangular prism is ${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 circleArea(radius){ circleArea = Math.PI * (radius * radius); } circleArea(7.2); console.log(The area of the circle is ${circleArea}.);

// 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 volumeSphere(radius) { volumeSphere = 1.33333333333 * Math.PI * (radius * radius * radius); } volumeSphere(7.2); console.log(The volume of the sphere is ${volumeSphere}.);

// 6. Use console.log to test each function and output to the JavaScript console // Here are the values to test and the expected results // -- Area of rectangle that is 5 wide and 22 tall: 110 // -- Volume of a rectangular prism that is 4.5 x 12.5 x 17.4: 978.7499999999999 // -- Area of a circle that with a radius of 7.2: 162.8601631620949 // -- Volume of a spehere with a radius of 7.2: 1563.4575663561109
