Can anyone check my problem? (Finding the circumference)

OpenStudy (anonymous):

OpenStudy (anonymous):

I think my answer is either. A. or B.

OpenStudy (anonymous):

Im stuck between those two options, if theyre even correct.

ganeshie8 (ganeshie8):

one of them is correct

ganeshie8 (ganeshie8):

area is given as, 24 pi

ganeshie8 (ganeshie8):

using that find the r

ganeshie8 (ganeshie8):

\(\pi r^2 = 24 \pi\)

OpenStudy (anonymous):

24 x r= ? Like this?

ganeshie8 (ganeshie8):

\( r^2 = 24\)

OpenStudy (anonymous):

ohh... 3.14r^2=24

ganeshie8 (ganeshie8):

\(r = \sqrt{24}\)

OpenStudy (anonymous):

So D should be my answer?

ganeshie8 (ganeshie8):

Now, find the perimeter using r

OpenStudy (anonymous):

the perimeter?

ganeshie8 (ganeshie8):

perimeter = \(2 \pi r\)

ganeshie8 (ganeshie8):

sorry, circumference

OpenStudy (anonymous):

2 times 3.14 = radius

OpenStudy (anonymous):

wait...ok im confused now., x)

ganeshie8 (ganeshie8):

circumference = \(2 \pi \sqrt{24} \)

ganeshie8 (ganeshie8):

circumference and perimeter are two words for same thing.

ganeshie8 (ganeshie8):

u need to simplify
