Answer:
At convergent point of plate boundaries, sedimentary rock that is present at ocean floor is pushed down into mantle. Due to the continuous movement of rock into the mantle increase the crust the temperature. Thus after continuous rise of temperature, crust melts down and eventually rise to surface of earth in the form of volcanic eruption. and after cools down gives rise to formation of igneous rock.
Explanation:
Process of igneous rock is given below

<span>first thing you need to do is find the area of the circle
A=(pi)r^2
You don't know r, but you do know the diameter is 10, and the diameter is twice the radius so r=5
Then plug that into the area formula, and you'll get A=25pi or 78.54 ft^2
If one bag covers 2 ft^2, then divide your area by 2 and round up to get the number of bags of concrete (40)
hope i helped !!!</span>
The answer is A. Sorry if i'm wrong.
