Instruction: Please write this code in javascript and let me know if there is an issue. Questions 1. Description a). You are to develop a JavaScript file (problems.js) that contains the implementation of 5 functions. Each function is represented as one step,  b). Each function is independent and solves a unique problem, as such, treat and implement each function in isolation of the others, that is, you should only focus on one problem at a time.  2). Objective • Write decision-making statements and control structures to solve problems • Apply programming logic to solve basic to intermediate problems • Testing and debugging

Questions

1. Description

a). You are to develop a JavaScript file (problems.js) that contains the implementation of 5
functions. Each function is represented as one step, 
b). Each function is independent and solves a unique problem, as such, treat and implement each function in isolation of the others, that is, you should only focus on one problem at a time. 

2). Objective

• Write decision-making statements and control structures to solve problems
• Apply programming logic to solve basic to intermediate problems
• Testing and debugging 

Function 3: Volume of Cylinder
function _three (radius, height)
Create a JavaScript function that meets the following requirements:
Receives two parameters, one representing a radius value, the other a height value
o The function can safely assume, all parameters passed are represented in meters (m).
The function calculates the volume of a cylinder and returns the value back to its caller.
The function always displays the calculated volume, rounded to two significant digits
• The function displays the calculated information (console log) as illustrated below:
The function returns the calculated volume back to the caller
Calling _three(5, 25)
The calculated volume is: 1963.50
Calling _three(0, 25)
The calculated volume is: 0.00
Calling _three(-5, 25)
Radius and height must be greater than 0

Function 4: Class Grading
function _four( array )
Create a JavaScript function that meets the following requirements:
Receives a variable length array of numbers, representing student grades in a course
The function traverses the array to determine the number of passing and failing grades.
A passing grade, is grade greater than or equal to 50
The function displays the count (console log) for the number passing grades, failing grades and overall
class average as illustrated below
Average class grade is rounded to 1 decimal point
The function returns the array containing the number of passing grades, the number of failing grades, and
the overall averages of the grades, respectively, back to the caller
Calling _four([50,51,80,45])
The number of passing grades: 3, failing grades: 1, and class average: 56.5
Calling _four([35,45,25,10,6,33])
The number of passing grades: 0, failing grades: 6, and class average: 25.7
Calling _four([80,90])
The number of passing grades: 2, failing grades: 0, and class average: 85.0
