\[50.27 ^{2}\]

OpenStudy (anonymous):

50.27 in^2 Is that the answer

OpenStudy (anonymous):

The circle's area is pi r^2 The radius is 4, so square that and you get 16. Multiply that by pi and you get 50.27. There is no need for the square to stay there, though.

Wait

OpenStudy (anonymous):

Okay thx. Could you check one more problem for me

OpenStudy (anonymous):

I can try

OpenStudy (anonymous):

I think you do have to keep the square after your answer. It would be 50.27in^2

Is the area 95.03 m^2

OpenStudy (anonymous):

The radius would be 5.5, which is 11 in half. After you square it and multiply it by pi, you get 95.03. Keep the unit and square, so yes your answer is correct :)
