Distance around half circle, is same as half the circumference

ok

OpenStudy (solomonzelman):

\(\color{#000000 }{ \displaystyle {\rm C}=2\pi r }\) Where, C - circumference r - radius

OpenStudy (johnnewman):

I got 219.80

OpenStudy (solomonzelman):

So, you can find the full circumference, and then divide the result by 2.
