"Rhaid i fi weithio'n galed."

Translation: I must work hard.

[Anneke69]

would hard on its own be "yn galed"?

[shwmae]

"Hard" as an adjective is caled and as an adverb yn galed.

[Anneke69]

Diolch yn fawr!

I must work hard or I have to work hard?

[shwmae]

They're the same in Welsh.

i was taught i have to or i must for rhaid i fi so why when i translate the sentence as i have to work hard is it marked wrong?

[speakwelsh.today]

That was my point. I didn't report it as a mistake, because I was unsure whether it would be considered bad English. If it comes up again I will report it.

[nuttyjoon]

i have just reported it as i agree with you on the translation

diolch!
