// 1. Attach this file geometry.js to the index.html file

console.log('connected!');

// 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 getArea (width, height) { var area = (width * height); return area; } console.log(getArea(5, 22));

// 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 getVolume ( width, height, length) { var volume = (width * height * length); return volume; } console.log(getVolume(4.5, 12.5, 17.4));

// 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 getCircleArea (radius) { var circleArea = (Math.PI * Math.pow(radius, 2)); return circleArea; } console.log(getCircleArea(7.2));

// 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 getSphereVolume (radius) { var sphereVolume = (4/3 * Math.PI * Math.pow(radius, 3)); return sphereVolume; } console.log(getSphereVolume(7.2));

// 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
