Answer 1

You can try this code

protected $priceHelper;

public function __construct(
    \Magento\Framework\Pricing\Helper\Data $priceHelper
) {
    $this->priceHelper = $priceHelper;
}

public function getFormattedPrice($price)
{
    return $this->priceHelper->currency($price, true, false);
}

Using Object Manager [Not Recommended way]

<?php
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); // Instance of Object Manager
    $priceHelper = $objectManager->create('Magento\Framework\Pricing\Helper\Data'); // Instance of Pricing Helper
    $price =  1000; //Your Price
    $formattedPrice = $priceHelper->currency($price, true, false);
?>

Hope It helps.
