Distance around half circle, is same as half the circumference
OpenStudy (johnnewman):
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.
