Help with units in PI

[purplelila2]

please help what are we doing wrong 😭😭😭😭
We can't seem to figure out the answer

36pi mm

Area = pi x (r squared)

Oops - unit should be mm squared I think

Area of circle is pi * r^2

Radius is half the diameter - in this case 6mm.
So 6^2=36
Therefore it would be 36pi aand units mm2 (as you have done 2 for the number you also do it for units)

The units are square mm.

@CuckooCuckooClock nope saying it's not correct😪

The unit is wrong - needs to be squared

36mm square is also incorrect? so confused!

Not looked at the answer but that website does my head in. So many times we have the answer but can't work our how maths watch wants it in put. Sorry rant over!

So the answer is 36pi
The units are mm squared

@sm40 that's the issue We have the answer and we're pretty sure the answer to the Units is also correct as confirmed by posters above but still saying our units are incorrect!

You dont need a number where its asking for the units so it's just mm²

Stop putting 36 in with the units

@dementedpixie thank you!
we didn't need to put the 36 in there

Plus the answer would have been 113.1mm² anyway

@dementedpixie - the question asked for the answer in terms of pi. So the correct answer is 36π mm².

That's not what the OP input though. One of their answers they put in for units was 36mm² and that's the one I was saying was wrong as it should just be mm²

OP had the correct answer for the first bit when expressing in terms of pi. She was questioning the answer when it asked for the units only.
