Area= pie • radius square
Since it’s diameter you divide it by 2 so it would 10. 10= radius, now does you multiply it by its self so 10•10= 100. Now multiply it but pie which it 3.14. 100•3.14= 314. 314 should be your answer!
Sorry if you get this wrong :( but I’m learning this and I usually get these right but best of luck! :)
