Mathematic formulas

Name the formulas for the shapes etc. Sorry if this quiz is bad but I'm still editing it and will add more questions.
don't use slash for division. Write it out in words. Use x or angle or etc.
Use numbers and say times not multiply etc
there will probably be answers which I need to edit so tell me in the comments what to edit
