For our first
assignment, i teamed up with four members (Felicia Tiong, Lee Qian Ying, Vicky
Lee, and Ricky Wong) to complete this assignment.
In order to find out the
total surface area and the volume of an object given in the question paper, we
had a small discussion when having a break. The first step to do was, we used
the Law of Sines to find the angle of part of a triangle on combined
circle, and get the area of segment.
Inside the object, there was
a prism-shaped. We tried to find the length of the prism and get the area of
it. Next, we had to find the area of cylinder (2πr² x 2πrh), then added all of the areas we found together to obtain
the total surface area of the object.
Finally, we found the volume
of the prism and cylinder. These are our calculation:
After the calculation, we
then constructed the object.
In this assignment, I found
that I can solve the trigonometry and the area and volume of an object more easily.
I was once weak at finding in areas and volumes when it came to a rather
difficult-shaped object. However, I can solve it calmly and without any struggle.
