What is the arc length if θ = 2 pi over 7 and the radius is 3 cm?

Length of the arc will be 2.69 cm.

Step-by-step explanation:

We have to calculate the length of an arc if θ = and radius of arc is 3 cm.

As we know length of an arc = r × θ

By putting the values of angle θ and radius of arc r in the formula

m (arc) =   × 3

           =  

           =  

           = 2.69 cm

Therefore, length of the arc will be 2.69 cm.

I believe the answer is C) The present continents appear to fit together as pieces of a larger landmass.

Explanation: The theory of continental drift is the shift position on Earth surface moved by tectonic plates.
