Presumably you should be doing this using calculus methods, namely computing the surface integral along 
.
But since describes a sphere, we can simply recall that the surface area of a sphere of radius 
is 
.
In calculus terms, we would first find an expression for the surface element, which is given by
So the area of the surface is
as expected.

Answer: Both students are correct.
Explanation:
In rotation a shape is rotated about a fixed point and it does not affect its measurements. it only changes its position.
Now, When Marcus rotated the about point S then this process did not affect its shape and size this is why he got the
which is congruent to the
.
In reflection, when a shape reflected across a line then its all points get reflected across this line. But it also does not affect the measurement of the shape.
So, when Sam mapped by the reflection of
then the measurement of the
did not change. And, he also got the congruent triangle.
Thus, we can say that, Both Marcus and Sam are right.
