Answer

16\pi or 50.24 units

Explanation:

\pir^{2} and r is the radius, since we know what the radius is (<em>r </em>) we can put this in to an expression

\pi · 4² = 16 units

If the answer is not 16 then its 50.24 units

Explanation:

Now 16 is the correct answer but just in case I took this a step further.

If we estimate the area by using 3.14 which is ( \pi ) because sometimes that isn't  natural to express the area using \pi

I hope I helped you : )

lorasvet [3.4K]

Answer:

<u>e. All convergent plate boundaries are subduction zones</u>

  • These collisions thus lead to the creation of mountains and volcanoes at greater altitudes as the place gets elevated and as a result of the slab push and pull as many earthquakes generally occur in this shallow zone also named as the Benioff zone.
  • Plates dip here at an angle of 45 degrees and thus form these internal subduction zones that lead to lithospheric density differentiation
