Answer:
The correct answer is 3πcm
Step-by-step explanation:
The length of an arc is calculated using the formula P=∅/360×2πr
where ∅is the angle the arc subtends at the center of the circle, and r is the radius of the circle of which the arc is part.
2r gives the diameter which from the diagram corresponds to AB=36 cm
therefore P=30/360×π×36
=3πcm
5pi is the answer

9/3000x 100% = 0.3%
We divide 9/3000, multiply result by 100.
If we had 20 from 500 people who were sick, we do 20/500*100= 4 %
