Find the value of integral ∫ C ( x + y + z ) d z , where C is parametrized by → r ( t ) = ⟨ 17 sin ( 5 t ) , 15 cos ( 5 t ) , 8 cos ( 5 t ) ⟩ for 0 ≤ t ≤ π .

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c

The answer is d. 16^2 + 63^2 = x^2hope this .
