// 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){
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
function volmueOfRectangularPrism(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^
function areaOfCircle(radius){
return 3.14 * 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
function volumeOfSphere(radius){
return 4/3 * 3.14 * 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

54,972 PointsYou could use Math.PI instead of 3.14.
boi
14,242 PointsYou could....... solve it better. Sigh Sigh.
const areaOfRectangle = (width, height) => width * height;
const volmueOfRectangularPrism = (width, height, length) => width * height * length;
const areaOfCircle = radius => 3.14 * Math.pow(radius,2);
const volumeOfSphere = radius => 4/3 * Math.PI * Math.pow(radius,3);
console.log('', areaOfRectangle(3,3),'\n', volmueOfRectangularPrism(3,3,3),'\n', areaOfCircle(3),'\n', volumeOfSphere(3));
