Answer 1

This is what you want exactly. By using the jQuery roundSlider plugin you can make any type of arc slider with custom appearance.

Please check this jsFiddle for the demo of you requirement.

Live demo:

$("#arc-slider").roundSlider({
    sliderType: "min-range",
    circleShape: "custom-quarter",
    value: 75,
    startAngle: 45,
    editableTooltip: true,
    radius: 350,
    width: 6,
    handleSize: "+32",
    tooltipFormat: function (args) {
        return args.value + " %";
    }
});

#arc-slider {
    height: 110px !important;
    width: 500px !important;
    overflow: hidden;
    padding: 15px;
}
#arc-slider .rs-container {
    margin-left: -350px; /* here 350 is the radius value */
    left: 50%;
}
#arc-slider .rs-tooltip {
    top: 60px;
}
#arc-slider .rs-tooltip-text {
    font-size: 25px;
}
#arc-slider .rs-border{
    border-width: 0px;
}

/* Appearance related changes */
.rs-control .rs-range-color {
    background-color: #54BBE0;
}
.rs-control .rs-path-color {
    background-color: #5f5f5f;
}
.rs-control .rs-handle {
    background-color: #51c5cf;
}

<link href="https://cdn.jsdelivr.net/jquery.roundslider/1.0/roundslider.min.css" rel="stylesheet"/>

<div id="arc-slider" class="rslider"></div>

Please check this LINK, you will get enough details for the slider.

'slide': function(e, ui){
var percentLeft;
var submitValue;
var Y = ui.value - 100; //Find center of Circle (We're using a max value and height of 200)
var R = 100; //Circle's radius
var skip = false;

$(this).children('.ui-slider-handle').attr('href',' UI.val = ' + ui.value);

//Show default/disabled/out of bounds state
if ( ui.value > 0 && ui.value < 201 ) { //if in the valid slide rang
$(this).children('.ui-slider-handle').addClass('is-active');
}
else {
$(this).children('.ui-slider-handle').removeClass('is-active');
}

//Calculate slider's path on circle, put it there, by setting background-position
if ( ui.value >= 0 && ui.value <= 200 ) { //if in valid range, these are one inside the min and max
var X = Math.sqrt((R*R) - (Y*Y)); //X^2 + Y^2 = R^2. Find X.
if ( X == 'NaN' ) {
percentLeft = 0;
}
else {
percentLeft = X;    
}
}
else if ( ui.value == -1 || ui.value == 201 ) {
percentLeft = 0;
skip = true;
}
else {
percentLeft = 0;
}

//Move handle
if ( percentLeft > 100 ) { percentLeft = 100; }
$(this).children('.ui-slider-handle').css('background-position',percentLeft +'% 100%'); //set new css sprite, active state

//Figure out and set input value
if ( skip == true ) {
submitValue = 'fail';
$(this).children('.ui-slider-handle').css('background-position',percentLeft +'% 0%'); //reset css sprite
}
else {
submitValue = Math.round(ui.value / 2); //Clamp input value to range 0 - 100
}   
$('#display-only input').val(submitValue); //display selected value, demo only
$('#slider-display').text(submitValue); //display selected value, demo only
$(this).prev('.slider-input').val(ui.value); //Set actual input field val. jQuery UI hid it for us, but it will be submitted.

Alternative way you can use this plugin for a curved/360 degree slider

Reference

Here is the coding:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="js/round-slider.min.js"></script>

 <div class="box dotted">
 <div class="left">
 <div id="degrees" class="demo"></div>
 </div>
 <div class="right">
 <p class="name">Degrees</p>
 <p id="degrees-data"></p>
 </div>
 </div>

Javascript

 (function($){
 'use strict';

 var set_html = function(value, index, angle, unit){

 var html = ''
,val = value;

 if(unit !== ''){
 val += unit;
 }

 html += '<b>Value: </b>' + val + '<br/>';
 html += '<b>Index: </b>' + index + '<br/>';
 html += '<b>Angle: </b>' + angle + '<br/>';

 return html;
 };

 $('document').ready(function(){

 var self = {
 degrees: null
 };


 self.degrees = $('#degrees').round_slider({
 min: 0,
 max: 359,
 unit_sign: '\u00b0',

 bg: 'img/bg/degrees-theme.png',
 handle_bg: 'img/handles/wheel-33-33.png',
 input_bg: 'img/input/round-50.png',
 points_bg: 'img/points/degress-white.png',

 angle_changed_callback: function(value, index, angle, unit){
 $('#degrees-data').html(set_html(value, index, angle, unit));
 }
 });
 });

 })(jQuery);
