The m angle MHA = 40° and diameter MT is 10. Calculate the length of arc AT .

answers:
12.2
24.4
6.1
16.2

Answer 1

\[C=\pi d\]\[C_{arc}={\theta\over360}\pi d\]where \(\theta\) is the angle measure of the arc, in this case 140 since 40+140=180, and d is the diameter

so:\[C_{arc}={140\over360}\times\pi\times(10)\] so just solve that and you'll find your answer :)

Answer 2

let me know if you still need help!

Answer 3

12. 2 ?

Answer 4

i was doing (10pi)

Answer 5

but thank you.(:

Answer 6

yup :) 12.2

Answer 7

lol yeah, just remember that the arc length the just the percentage (angle over 360) times circumfrence :)

Answer 8

okay(:
