JavaScript The Solution

Please Review, Thanks

// 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

const area = (width, height) => { return width * height; }

// 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

const volume = (width, height, length) => { return width * height * length; }

// 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

const circleArea = (radius) => { return Math.PI * Math.pow(radius,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

const sphereVolume = (radius) => { return (4/3) * Math.PI * Math.pow(radius,3); }

// 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

console.log(area(5, 22) ); console.log(volume(4.5, 12.5, 17.4) ); console.log(circleArea(7.2) ); console.log(sphereVolume(7.2) );
