Malia is placing a barrier around the edge of a circular path with a diameter of 13 meters. The barriers are in lengths of 2.5 m

Bezzdna [24]

Answer:

B. 17

Step-by-step explanation:

We have been given that Maria is placing a barrier around the edge of a circular path with a diameter of 13 meters.

Since we know that circumference of a circle equals $2\pi r$ , where,

r= Radius of the circle.

Since we have been given the diameter of the circular path, so let us divide our given diameter by 2 to find radius of our circular path.

$\text{Radius of circular path}=\frac{13}{2}=6.5$

Let us find the circumference of our circular path.

$\text{Circumference of circular path}=2*3.14*6.5$

$\text{Circumference of circular path}=40.82$

Since circumference of circular path is 40.82 meters, so to find the number of pieces of barrier we will divide circumference of circular path by length of each barrier.

$\text{Number of barriers used}=\frac{40.82}{2.5}$

$\text{Number of barriers used}=16.328$

As the barrier will be used as a whole piece, therefore, Malia needs 17 pieces of barrier and option B is the correct choice.

Which theory of migration states that people sailed down the west coast of North America to make settlements?

lara31 [8.8K]

The appropriate answer is b. the Northern Asia Coastal theory. This theory states that people entered North America by moving along the coast from north west Asia along the northern Pacific coastline using rafts or early designs of boats. It was previously thought that people entered north America by crossing the Bering Strait but new evidence contradicts this theory.
