what goes in the place of "mc088-2.jpg"

anonymous · Answer

arc abc

jim_thompson5910 · Answer

what's the circumference of this circle?

anonymous · Answer

its on the image 24 ft

jim_thompson5910 · Answer

that's the diameter

jim_thompson5910 · Answer

what's the distance around the full circle

anonymous · Answer

idk 360?? i think

jim_thompson5910 · Answer

C = pi*d

C = circumference
d = diameter

jim_thompson5910 · Answer

what's the circumference if the diameter is 24

anonymous · Answer

75.36

jim_thompson5910 · Answer

leave it in terms of pi, so it's just 24pi

jim_thompson5910 · Answer

now minor arc AC is 30 degrees (given)

so major arc ABC is 330 degrees (since 330 + 30 = 360 degrees)

jim_thompson5910 · Answer

you now use this formula


s = (angle/360)*C

where 

s = arc length 
C = circumference

in this case, C = 24pi and s is unknown for now, meaning that


s = (angle/360)*C

s = (330/360)*24pi

s = ???
