Your second question, I have problems with, first of all you use acurve, this is not an irregular shape, then you find the surface areausing a formula that you do not explain, and it is not your example,it is copied from someone else. The leaf also does not appear to beyour example or calculations. My question says to pick an irregularshape of an object, draw or take a picture of that object and alsoexplain how you would calculate its surface area and volume, that isnot what you have done.
Question 3 also is not adequate. The question specifically talks aboutintegrating methods. Completing the square is not an integratingmethod, it is a method to solve quadratic equations. You have alsoprovided 2 examples of completing the square (which do not appear tobe your own) and there isn’t any integration in sight, so I am afraidthat you have not answered this question properly either.Re-read the questions carefully, and the marking criteria. Provide allthat is asked and you will get full marks, otherwise it will nothappen. Also make sure that any examples you provide are your own
