Hourly pricing on SQL database Provisioned VS Serverless

Hi,

I've beed searching and using the azure calculator to approximate a budget for a project I'm working on.

Question 1: If the Provisioned tier doesn't have auto pause-resume, and you don't stopped manually ¿Why Azure calculator offers you to calculate price in a hourly demmand?

Question 2: If the Serverless tier does have auto pause-resume, ¿Why Azure calculator doesn't offers you to calculate price in a hourly demmand? I trying to figure out the price of Serverless just for 10 hours of activity before the automatic stop takes effects.

Best regards

Jona
