iPad (9th generation) screen replacement
My ipad screen is cracked how much is it to replace it
You can check availability/eligibility for repair - and associated cost for your country/region - here:
iPad Repair & Service - Apple Support
In addition to Apple's mail-in repair service, you can arrange repair at the Genius Bar of your local Apple Store or Apple Authorised Service Provider (AASP):
Genius Bar Reservation and Apple Support Options - Apple
For practical purposes, in lieu of servicing and returning your own iPad, Apple usually exchange the iPad for a renewed/refurbished iPad of the same model and specification. The cost of the exchange is the same as would otherwise be charged for a screen replacement.
If you have an active AppleCare+ plan, the cost of repair is reduced to a small excess/deductible fee.
